Question

$$10(10+(-30))+15(5+30)-8\times(-7)$$

Evaluate

$381$

Solution Steps

Subtract $30$ from $10$ to get $-20$.

$$10\left(-20\right)+15\left(5+30\right)-8\left(-7\right)$$

Multiply $10$ and $-20$ to get $-200$.

$$-200+15\left(5+30\right)-8\left(-7\right)$$

Add $5$ and $30$ to get $35$.

$$-200+15\times 35-8\left(-7\right)$$

Multiply $15$ and $35$ to get $525$.

$$-200+525-8\left(-7\right)$$

Add $-200$ and $525$ to get $325$.

$$325-8\left(-7\right)$$

Multiply $8$ and $-7$ to get $-56$.

$$325-\left(-56\right)$$

The opposite of $-56$ is $56$.

$$325+56$$

Add $325$ and $56$ to get $381$.

$$381$$

Factor

$3\times 127$
