A

Algebraic Expression
An expression consisting of one or more variable and an arithmetic.
 * Example**: 6y+3

Additive Identity Property- For any number a, the sum of a and 0 is a, a+0=a
 * Example:** 5+0=5

= =

=**Addition Words**=

These are words that indicate "addition" like "add", "plus" ,"increase by"


 * Examples**: 2+3=5 or5+6=11

=Additive inverse property - When a number and it's negative ( or opposite) are added together, the sum is 0 (symbol a-a = 0, or a+ (-a)=0) = (example 5-5=0 5+(-5)=0)
