Question

Rewrite the expressions with parentheses to equal the given value. 3x4-1+2

Answer 1

3 x 4 - 1 + 2

With parentheses would be - (3x4) - (1+2)

This is because either way, you would still do the multiplication first because of the rule of PEMDAS/GEMDAS which states that parentheses and grouping symbols go first.

Answer 2

3×4-1+2=11
3x(4-1)+2=11

5+3×2-6=10
(5+3)×2-6=10

Hope this helps ;)
