Question

How do you know that the expression 12 + 4y is represented as "the sum of 12 and the product of 4 and y?" Explain your thinking then choose one student who explains their thinking differently than yours. Respond to their statement appropriately to help them understand why their response is correct or incorrect.

Answer 1

"sum" means added together, "product" means multiplied

Explanation:

Word problems like this are fun. If you're taking the sum of x and y, you write that as x+y. If you take the product of x and y, that is written xy. the sum of a number and the product of 5 and 6, means the two terms will be added, but the latter term is a multiplier of 5 and 6.

Or, in algebra, this would be (x + (5)(6))
