Major Styles of Input
(more...)

- Spaces around mathematical symbols (+-*/:()=%), commas, and semi-colons are optional, but required between "x" and a non-numeric operand. (e.g. "1+1", "2 + 3", "2x4", "length x width")
- Most punctuation symbols (.,;?!) can be used normally.

Major Categories of Input (more...)

- AutoMathic does NOT handle "yes or no" questions. (e.g. "Is the mass 5 unit kg?")
- Any inconsistency must be resolved following such a warning message.
- Kernel commands may not be mixed with other input, and must begin with the "Kernel escape" character. It is "!" by default, but may be redefined in the "config" setup file or using a kernel command (e.g. "!set c_kernel_esc=#")
- By default, AutoMathic will utilize its library without asking unless the "b_auto_consult" option is set to "0".

- Numbers may contain commas (,) as group separators. (e.g. 1,000,000)
- Decimal fractions between -1 and 1 MUST have a leading zero. (e.g. -0.125)
- Numbers may NOT be entered using scientific notation. (e.g. 3.215e-9)

- Written numbers can always be combined as long as the combination is multiplicative, not additive. (e.g. "three hundred", "five sixteenths")
- Contrary to standard spelling conventions, AutoMathic's combined numbers must NOT be hyphenated. (e.g. "two-thirds")
- Additive combinations of numbers are safe when they are not part of a larger term. (e.g. "three and a half")
- Complicated written numbers (that imply multiplication and addition) are usually NOT understood by AutoMathic. (e.g. "two hundred fifty six")
- The only way to use an additive combination as part of a larger term is to enclose the combination within parentheses to help guide the translation. (e.g. "(three and a half) thousand")
- It is most effective to use written numbers for the simple cases and multiplicative combinations only.

- If every measurement of the same type (e.g. length) uses the same units, the units can be left off entirely.
- Units must be used when two or more measurements of the same type (e.g. distance) use different units of measurement.
- If units are used for a type of measurement, include units for every measurement of that type.

- Unit abbreviations must NOT include periods (e.g. "ft.") unless of course it appears at the end of a sentence.
- Built-in abbreviations of compound units (e.g. MPH, FPS, RPM) can be treated as simple units and not be parenthesized.
- In Unit Phrases, simple or compound units can be enclosed in square brackets to simplify and shorten the unit phrase.
- Put "measured in", "in unit", or one of their variants, between a property and its unit. (e.g. "length measured in inches", "length in [inches]")
- Put "unit" or "units" between a quantity and its unit (e.g. "15 unit cm"), unless the unit is enclosed in square brackets. (e.g. "15[cm]")
- A compound unit following a quantity must be enclosed in parentheses or square brackets. (e.g. "15 unit (miles per hour)", "15[miles per hour]")
- Parentheses are optional for a compound unit following a property. (e.g. "speed in unit miles per hour", or "speed in unit (miles per hour)")
- Parentheses are not required when a compound unit is enclosed in square brackets. (e.g. "speed in [miles per hour]")
- Units can be used by themselves (without scalars or properties) in a standalone fashion. (e.g. "miles per hour is 55")
- Unit phrases can be used by themselves to request a calculation. (e.g. "speed in units mph", "speed in [mph]")
- Unit phrases can be used in questions to ask for a measurement. (e.g. "How many unit MPH would the speed be?", "How many [MPH] would the speed be?")
- Unit phrases can be used in statements of fact to define a measurement. (e.g "The speed is 55 unit (mi/hr).", "The speed is 55[mph].")

- Unit conversions can be done with a statement defining a measurement and a request for the measurement in different units. (e.g. "If the mass is 3.2 unit tons, what's the mass measured in kg's?", "If the mass is 3.2[tons], what's the mass in [kg's]?")
- Unit conversions can be done with a direct question. (e.g. "What's 3.2 unit tons measured in kg's?", "What's 3.2[tons] in [kg's]?")
- Unit conversions can be done with statements based on the verb "convert":

e.g. Convert 55 unit mph into unit kph.

e.g. Convert 55[mph] into [kph].

e.g. 55 unit mph to units kph.

e.g. 55[mph] to [kph].

e.g. Convert 55 from unit mph to unit kph.

e.g. Convert 55 from [mph] to [kph].

e.g. 55 from units mph into units kph.

e.g. 55 from [mph] into [kph].

e.g. 55 converted from unit mph to unit kph.

e.g. 55 converted from [mph] to [kph].

e.g. How many unit kph converts to 55 unit mph?

e.g. How many [kph] converts to 55[mph]?

e.g. How many unit kph would 55 unit mph convert to?

e.g. How many [kph] would 55[mph] convert to?

- The following formal grammar describes AutoMathic's language for units:

unit:

<simple unit>

<compound unit>

unit-phrase:

<property> {MEASURED IN|IN TERMS OF} [UNIT[S]] <unit>

<property> {MEASURED IN|IN TERMS OF} "["<unit>"]"

<property> IN UNIT[S] <unit>

<property> IN "["<unit>"]"

<quantity> UNIT[S] <simple unit>

<quantity> UNIT[S] (<compound unit>)

<quantity> "["<unit>"]"

<unit>

<unit-phrase>

[CONVERT] <unit-phrase> {IN|TO|INTO} UNIT[S] <unit>

[CONVERT] <unit-phrase> {IN|TO|INTO} "["<unit>"]"

[CONVERT] <quantity> FROM UNIT[S] <unit> {IN|TO|INTO} UNIT[S] <unit>

[CONVERT] <quantity> FROM "["<unit>"]" {IN|TO|INTO} "["<unit>"]"

<quantity> CONVERT[S|ED] FROM UNIT[S] <unit> {IN|TO|INTO} UNIT[S] <unit>

<quantity> CONVERT[S|ED] FROM "["<unit>"]" {IN|TO|INTO} "["<unit>"]"

<unit-phrase> CONVERT[S|ED] {IN|TO|INTO} <unit-phrase>

<unit-phrase> <helping-verb> <unit-phrase> CONVERT[S|ED] {IN|TO|INTO}

Temperature Conversion (more...)

- Unit conversions for units that are not simple ratios of each other (e.g. temperature scales) must be done using property-based unit phrases. (e.g. "temperature measured in Celsius", or "temperature in units Fahrenheit")

Mathematical Operators (more...)

- "+" - plus, added to, more than, larger than, greater than, bigger than, higher than, later than, longer than, wider than, taller than, deeper than, broader than, hotter than, heavier than, faster than, quicker than, older than

and, &, less, smaller, fewer,

- AutoMathic does not support exponents, roots, or high-level math functions.

- AutoMathic creates variables out of nouns and noun phrases.

Nouns and Noun Phrases (more...)

- Noun phrases that include restrictive clauses get simplified. (e.g. "cars that are red" simplifies to "red")
- AutoMathic cannot handle problems requiring more than 52 variables.

- AutoMathic can be explicitly told that unmatched references to the same thing are the same via a statement of fact. (e.g. "goose means geese")

- Quantity words that are part of a larger noun phrase have a different interpretation than quantity words used by themselves. (e.g. "percentage", "number", "amount", "fraction", "quantity", "part", "portion", "multiple")
- Quantity words and mathematical constants (e.g. Pi, Tau, e, Golden Ratio, C), are the only classes of nouns that have special meaning to AutoMathic.

- AutoMathic automatically solves for nouns that start with "what" or "how much". (e.g. "Half of the total is what value?")
- AutoMathic automatically solves for implicit nouns that arise from generic "how much", "how many", and "what" questions. (e.g. "Six times how many is a dozen?")

Mathematical Expressions (more...)

- A mathematical expression is some arithmetic combination of
numbers, operators, and variables.

Requests for calculation and simple questions translate into mathematical expressions. - If AutoMathic says that it "didn't understand" something, always rephrase the input to let it try again.
- Questions usually use a form of the verb "to be".
- AutoMathic does NOT handle "yes or no" questions! (e.g. "Is the mass 5 unit kg?")

Mathematical Equations (more...)

- A mathematical equation is simply two mathematical expressions joined by an equals sign (=).
- Any assertion or statement of fact translates into an equation.
- In Algebraic style, equations are literally created by joining two mathematical expressions with an equals sign.
- In Simple Translation, equations are usually created using variations of simple synonyms or idioms for the equals sign (e.g. "equals", "is", "are", "was", "were", "make", "makes up", "gives", "yields", "results in").
- In Natural Language, equations can come from sentences with almost any verb phrase based on the verb "to be".
- In Natural Language, non-trivial questions can produce equations (which themselves are "statements-of-fact").
- Statements of fact create equations and/or assign values to variables.
- Equations with no variables are ignored.
- Statements of fact involving one "thing" assign a value to its variable.
- Statements of fact involving two or more "things" form an equation relating them.

- A contradiction involving a single "thing" redefines its variable value, and undefines any dependent variable values.
- A contradiction involving multiple "things" is accepted, but with a warning that the equation is "Overdetermined, and the system is Inconsistent". It must be resolved for results to be valid.
- A contradiction can be resolved by removing the inconsistent equation.
- A contradiction can be resolved by redefining or clearing one or more contradictory variables.
- AutoMathic does not automatically do anything more than detect and report inconsistency.

Indirect References via Pronouns (more...)

- Leading pronouns in a noun phrase are ignored. Differentiate noun phrases with something other than leading pronouns.
- In AutoMathic, pronouns refer to nouns, not necessarily entire noun phrases.
- In AutoMathic, pronouns refer to the most recent noun the user referred-to, or...
- ... Pronouns refer to the most recent answer provided by AutoMathic.
- Simple follow-up questions that use a pronoun to refer to the last result can be used to do a calculation bit-by-bit.
- Nouns introduced by AutoMathic, pseudo-nouns (Pi, e, etc.), and "generic" nouns (e.g. "number", "amount", "portion", etc.) do not overshadow the user's nouns as referents of a pronoun.

- Additional dialogue unrelated to the current situation should be done in a different AutoMathic session.
- Simple follow-up questions that use a pronoun to refer to the last result can be used to do a calculation bit-by-bit.
- "No Change" follow-up questions simply ask for new information without changing anything.
- "Simple Change" follow-up questions simply change one or more variables.
- "Simple Change" follow-up questions may require the user to redefine one or more independent variables if they got undefined in the process.
- The "lock" kernel command can be used before a Simple Change to prevent independent variables from being automatically undefined.
- "Complex Change" follow-up questions change one or more existing equations.
- "Complex Change" follow-up questions usually create contradictions that MUST be resolved.
- Retracting an existing equation must be done using the Kernel Mode "remove" command.
- Use the Manual or Automatic method to redefine or derive consistent variable values.
- After a Complex Change, you may need to re-state your request to get the consistent and correct answer.
- "No Change" and "Simple Change" follow-up questions are always safe to ask.
- It may be better to avoid Complex changes entirely and simply restate the problem (with the changed assumptions) in a new AutoMathic session.
