Simplify: ÷ 6 ∙ 2

Order of Operations PleaseExcuseMyDearAuntSally

Exponents and Powers Evaluate 3 4

Exponents and Powers Evaluate is the _______________ 3 is the _______________ Power is the product of equal factors.

Exponents and Powers What is the difference between (3x) 2 and 3x 2

Simplify these numeric expressions 6 ÷ 3 ∙ (6 ÷ 3 ∙ 2) (6 ÷ 3) ( ) 6 ÷ (3 ∙ 2 3 ) + 9

Term ► Part of an expression. ► Can be a number, variable, or product of one or more numbers or variables.

Coefficient ► Number in front ► Numerical factor of a term

Like Terms ► Same variable raised to same power ► 3x 2 and -6x 2 ► -5a 2 b 3 and 10a 2 b 3 ► NOT LIKE TERMS: 10x 2 y and -5xy 2

Combine Like Terms ► Combine coefficients ► Use the same variable and coefficients
