Write a numerical expression to represent:
Problem 1: Write a numerical expression to represent: Double 5 then add 26 (2 x 5) + 26

3 times the difference between 29 and 18
Problem 2: Write a numerical expression to represent 3 times the difference between 29 and 18 3x(29-18) or 3(29-18)

12 more than the quotient of 81 and 9
Problem 3 Write a numerical expression to represent 12 more than the quotient of 81 and 9 12 + (81 ÷ 9)

Twice as much as the sum of 2.5 and 4
Problem 4 Write a numerical expression to represent Twice as much as the sum of 2.5 and 4 2(2.5+4) or 2 x (2.5 x 4)

Write a numerical expression to represent
Problem 5 Write a numerical expression to represent 2 less than the sum of and 3 2 5 ( ) – 2

5 less than the product of 7 and 8
Problem 6 Write a numerical expression to represent 5 less than the product of 7 and 8 (7 x 8) -5

Half the difference between 27 𝑎𝑛𝑑 15
Problem 7 Write a numerical expression to represent Half the difference between 27 𝑎𝑛𝑑 15 (27−15) ÷ 2

26 less the quotient of 22 and 11
Problem 8 Write a numerical expression to represent 26 less the quotient of 22 and 11 26 – (22 ÷ 11)

Write a numerical expression to represent
Problem 9 Write a numerical expression to represent 15 minus the sum of 6 plus 7 15 – (6 + 7)

Problem 10 Harper wrote the expression 15(n) to represent “ the quotient of 15 and n”. Do you agree or disagree with Harper? Justify your thinking.

Summarizer: Subtract 7 from 9, then multiply by 8 A. 9 x (8 - 7)
Match the following. On your recording sheet, write the number with the corresponding letter next to it. Then turn your paper into Miss Caponigro. Subtract 7 from 9, then multiply by 8 A. 9 x (8 - 7) 2) Multiply 8 times 9, then add 7 B x 8 3) Subtract 7 from 8, then multiply by 9 C x 9 4) The product of 8 and 9, minus 7 D. 8 x 9 - 7 5) 8 times the quotient of 9 and 7 E. 8 x (9-7)
