Question

$$70\div10+89\times2-65\times7+98+21$$

Evaluate

$-151$

Solution Steps

Divide $70$ by $10$ to get $7$.

$$7+89\times 2-65\times 7+98+21$$

Multiply $89$ and $2$ to get $178$.

$$7+178-65\times 7+98+21$$

Add $7$ and $178$ to get $185$.

$$185-65\times 7+98+21$$

Multiply $65$ and $7$ to get $455$.

$$185-455+98+21$$

Subtract $455$ from $185$ to get $-270$.

$$-270+98+21$$

Add $-270$ and $98$ to get $-172$.

$$-172+21$$

Add $-172$ and $21$ to get $-151$.

$$-151$$

Factor

$-151$
