Question

Add parentheses to the following equation to make it true.


`12*2-3+4*2=-4`

Answer 1

`12 * (2 - 3) + (4 * 2)`

Explanation:

Add parentheses to the following equation to make it true.

`12 * 2 - 3 + 4 * 2 = - 4`

________________

`= 12 * 2 - 3 + 4 * 2 = - 4`

`= 12 * (2 - 3) + (4 * 2)`

`= 12 * ( - 1) + 8`

`= - 12 + 8`

`= - 4`

Answer 2

`12 * (2 - 3) + (4 * 2)`

Explanation:

Follow PEMDAS for the given answer.

PEMDAS is the order of operation, and is:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

Reverse solve the answer so that the result is the question.

First, solve the parenthesis:

12 * (2 - 3) + (4 * 2)

12 * (-1) + 8

Next, multiply 12 and -1 together:

12 * -1 = -12

Finally, add:

-12 + 8 = -4

12 * (2 - 3) + (4 * 2) is your answer.
