Does the phrase "2 times the sum of a number and 5" represent the same expression as the phrase "the sum of 2 times a number and 5"?

Respuesta :

JiakSai

Let us assume that the unknown number is x.

"2 times the sum of a number and 5" means 2(x + 5).

"the sum of 2 times a number and 5" means 2x + 5.

Therefore, the above statements do not have the same mathematical meaning.
