Numerical Expressions

Translating Word Phrases into Numerical Expressions Addition Subtraction Multiplication Division plus minus times divided sum difference product of quotient more than less multiplied per increased by subtract each rate in all decreased by of ratio total less than factors separate

Translate these word phrases into numerical expressions: eleven more than fifteen 15 + 11 or 11 + 15 four less than eighteen 18 – 4 not 4 - 18 $20 per month for 5 months 20 • 5 or 5 • 20

Order of Operations Please Excuse My Dear Aunt Sally Parentheses – work inside grouping symbols first Exponents Multiply and Divide from left to right Add and Subtract from left to right

Evaluate the following numerical expressions: 18 ÷ 3 • 2 = 6(2 + 9) – 3 • 8 = 4[ (15 – 9) + 8(2) ] = 4) 56 ÷ (7 • 2) • 6 =
