Question

Which expression is equivalent to (2 + 3) + 5?
A) 2 + (3 + 5)
B) 2(3 + 5)
C) 2 + 15
D) 6 + 5

Answer 1

Let's start by eliminating some obvious answers.
D says 6 + 5, in the expression, (2+3) is done first and that's 5 not 6.
C is 2 + 15. Like I said for D, 2 + 3 = 5, and the next number is 5. Leaving A and B.
B shows multiplication 2 *(3 + 5). You can already eliminate that.

Leaving your answer A. It's the same sum.
