Order of Operations:

1. Work inside the parenthesis first. 2x3(5+2) = 2x3(7)

2. Multiply or divide from left to right. 2x3(5+2) = 2x3(7) = 6(7) = 42

$2\times 3(5+2)=2\times 3\times 5+2\times 3\times 2=30+12=\boxed {42}$ .

$2\times 3(5+2)=2\times 3(7)=2\times 21=\boxed {42}$ .

$2 \times 3 \times (5 + 2) \implies 6 \times 7 = \boxed{42}$
