VOCAB: Terms: a single number or

variable, or the product of several numbers or variables separated

from another term by a + or - sign Variables: letter representing a

number Combining Like Terms/Simplify:

terms that share the same variable, then combining them together

Examples:

1. 2 + 4 • -6 = PEMDAS

2 + (-24)=

•MDAS

-22
