Binomial

two terms connected by + or -

subtract

when dividing the same base, do this with the exponents

solid line

when graphing a linear inequality, if it is equal to use this

add

when multiplying the same base, do this with the exponents

the side across from the right angle in a right triangle

Zero

the slope of a horizontal line.

Undefined

the slope of a vertical line.

Least common multiple
