Question

$$-9-(-7+(-4+18\div6)-7)+15$$

Evaluate

$21$

Solution Steps

Subtract $4$ from $-7$ to get $-11$.

$$-9-\left(-11+\frac{18}{6}-7\right)+15$$

Divide $18$ by $6$ to get $3$.

$$-9-\left(-11+3-7\right)+15$$

Add $-11$ and $3$ to get $-8$.

$$-9-\left(-8-7\right)+15$$

Subtract $7$ from $-8$ to get $-15$.

$$-9-\left(-15\right)+15$$

The opposite of $-15$ is $15$.

$$-9+15+15$$

Add $-9$ and $15$ to get $6$.

$$6+15$$

Add $6$ and $15$ to get $21$.

$$21$$

Factor

$3\times 7$
