# Mathematical Operators

AutoMathic builds mathematical expressions and equations using the four primary arithmetic operators "+", "-", "*", "/", the equals sign "=", and the parentheses grouping symbols "(", and ")".  However, it knows many obvious and not-so-obvious synonyms and idioms for these symbols, allowing a wide range of expression:

 ` + ` 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, or, after, above, beyond, past, with ` - ` minus, takeaway, take away, from, off, under, before, below, sans, short of, subtracted from, taken from, taken away from, less than, smaller than, fewer than, shy of, sooner than, shorter than, narrower than, shallower than, colder than, lighter than, lower than, slower than, younger than more, larger, greater, bigger, higher, without ` * ` times, by, x, multiplied by ` / ` over, to, :, divided by, divided in, divided into, out of to, {in|on}
, unit

The equals sign (=) has many synonyms and will be discussed at length in the section on Mathematical Equations.

AutoMathic has no synonyms for the parentheses grouping symbols "(" and ")".  However, the interpretation of some phrases causes AutoMathic to include them as necessary.  Parentheses can be used almost anywhere, but they are most often used when following the Algebraic input style or specifying compound units.

Since AutoMathic is restricted to basic algebra, it does not have general support for exponentiation (e.g. "^", "**"), roots, or high-level mathematical functions.  However, AutoMathic does have limited support for understanding "^2", "^3", "squared", and "cubed" in the context of multi-dimensional units.
