Question

Part A

Sherry's teacher asked her to write an expression for the product of 6 and the sum of
4 and 5.
Sherry wrote the expression 6 x 4 + 5.
Did Sherry write a correct expression? Explain why or why not.

Answer 1

No she didnt write a correct expression

Explanation:

the correct expression should have been 6×(4+5) or 6×(5+4). Sherry found the product of 6,5, and 4, instead of the product of 6 and the sum of 5 and 4. In addition, the two expressions above are both correct because both do represent the product of 6 and the sum of 5 and 4. 5+4 and 4+5 are the same.
