Solve 6+4-[-3+1-(2-5+6)-4]-7

$$6 + 4 - [ - 3 + 1 - ( 2 - 5 + 6 ) - 4 ] - 7$$

Evaluate

$$12$$

Solution Steps

Add 6 and 4 to get 10.

$$10-\left(-3+1-\left(2-5+6\right)-4\right)-7$$

Add -3 and 1 to get -2.

$$10-\left(-2-\left(2-5+6\right)-4\right)-7$$

Subtract 5 from 2 to get -3.

$$10-\left(-2-\left(-3+6\right)-4\right)-7$$

Add -3 and 6 to get 3.

$$10-\left(-2-3-4\right)-7$$

Subtract 3 from -2 to get -5.

$$10-\left(-5-4\right)-7$$

Subtract 4 from -5 to get -9.

$$10-\left(-9\right)-7$$

The opposite of -9 is 9.

$$10+9-7$$

Add 10 and 9 to get 19.

$$19-7$$

Subtract 7 from 19 to get 12.

$$12$$

Factor

$$2^{2}\times 3$$
