Question

$$18(-7+16)-4(91-160)+5-(26+20)$$

Evaluate

$397$

Solution Steps

Add $-7$ and $16$ to get $9$.

$$18\times 9-4\left(91-160\right)+5-\left(26+20\right)$$

Multiply $18$ and $9$ to get $162$.

$$162-4\left(91-160\right)+5-\left(26+20\right)$$

Subtract $160$ from $91$ to get $-69$.

$$162-4\left(-69\right)+5-\left(26+20\right)$$

Multiply $4$ and $-69$ to get $-276$.

$$162-\left(-276\right)+5-\left(26+20\right)$$

The opposite of $-276$ is $276$.

$$162+276+5-\left(26+20\right)$$

Add $162$ and $276$ to get $438$.

$$438+5-\left(26+20\right)$$

Add $438$ and $5$ to get $443$.

$$443-\left(26+20\right)$$

Add $26$ and $20$ to get $46$.

$$443-46$$

Subtract $46$ from $443$ to get $397$.

$$397$$

Factor

$397$
