Question

Rewrite the expression with parentheses to equal the given value. 3 × 4 - 1 + 2 Value: 11

Answer 1

3 x (4-1) +2 = 11
= 3 x 3 + 2
= 9 + 2
=11

Answer 2

3 * 4 - 1 + 2 must be equal to 11

Let's put parenthesis in two different version and check. There is no importance putting it for the multiplication because in mathematics multiplication is the first order of operations. If we put it in this manner:

3 * 4 - (1 +2) the answer will be 12 - 3 = 9. So that, this is not the answer we were looking for.

If we put it in this manner:

3 *(4 - 1) +2 the answer will be 3 * 3 + 2 = 11. And it is the correct version.
