Operations with Expressions Review

PEMDAS – tells which operation is performed first so that everyone finds the same value for an expression

• algebraic expression

• perfect square

• term

• order of operations

In a power, the number that tells how many times the base is used as a factor

• coefficient

• constant

• exponent

• property

a math expression that contains numbers and at least one operation

• numerical expression

• algebraic expression

• order of operations

• equivalent expression

contains at least one variable and at least one operation

• numerical expression

• algebraic expression

• like terms

• equivalent expression

My first step will be to change the operator to multiplication and reciprocate the second fraction when...

• Adding

• Subtracting

• Multiplying

• Dividing

Match each topic with the operation it uses.

• Addition

• Combining Like Terms

• Multiplication

• Distributive Property

• Division

• Factoring

Think of a number x. Multiply it by 3 and add 5 to the product

• 5x+3

• x+5+3

• 3x+5

2 times the difference of t and 11

• 2t - 11

• 2(t - 11) 

• 2(t ÷ 11)

• 2 x t - 11

• coefficient

• constant

• power

• perfect square

The order in which numbers are added

or multiplied does not change the sum or product

• associative property

• commutative property

• distributive property

• identity property
