$9+3-(2+4)=6$
$9+3-(2+4)=6$ Use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) to solve this equation. 1. First, solve the numbers inside the parenthesis. $(2+4)=6$ 2. Next, use addition. $9+3-6=6$ is simplified to $12-6=6$. 3. Now, use subtraction. $12-6=6$, leaving you with $6=6$. By using PEMDAS, we were able to solve the left side of the equation and prove it is equal to the right side.
