Need to keep brackets

Answer 2

Answer:

The expression written by Sherry is wrong.

Step-by-step explanation:

Ms. Whittier’s statement: Product of 6 and the sum of 4 and 5.

This expression can be written as following:

The sum of 4 and 5 = (4 + 5)

The product of 6 and the sum of 4 and 5. = 6 x (4 + 5)

Sherry’s expression was: 6x4+5

According to Ms. Whittier, first the sum of 4 and 5 is to be found and then it is to be multiplied with 6.

But what Sherry wrote is wrong because, she first multiplied 6 and 4 and then added 5 to the product.
