Work Step by Step
The problem states to insert one set of parentheses to make the statement true. The original statement is:
8 - 2 $\times$ 3 - 4
Adding the parentheses as noted below makes the statement true (note the problem worked using order of operations):
(8 - 2) x 3 - 4
(6) x 3 - 4 working within parenthesis where 8 - 2 is 6
Then multiplication and division left to right.
18 - 4.
Last add and subtract left to right.
18 - 4 = 14
