3\times 3=2\left(1+2\right)-\left(1-4\right)
Add 1 and 2 to get 3.
9=2\left(1+2\right)-\left(1-4\right)
Multiply 3 and 3 to get 9.
9=2\times 3-\left(1-4\right)
Add 1 and 2 to get 3.
9=6-\left(1-4\right)
Multiply 2 and 3 to get 6.
9=6-\left(-3\right)
Subtract 4 from 1 to get -3.
9=6+3
The opposite of -3 is 3.
9=9
Add 6 and 3 to get 9.
\text{true}
Compare 9 and 9.
