Question

$$21 \div 3+7-5+(45 \div 5)+9$$

Evaluate

$27$

Solution Steps

Divide $21$ by $3$ to get $7$.

$$7+7-5+\frac{45}{5}+9$$

Add $7$ and $7$ to get $14$.

$$14-5+\frac{45}{5}+9$$

Subtract $5$ from $14$ to get $9$.

$$9+\frac{45}{5}+9$$

Divide $45$ by $5$ to get $9$.

$$9+9+9$$

Add $9$ and $9$ to get $18$.

$$18+9$$

Add $18$ and $9$ to get $27$.

$$27$$

Factor

$3^{3}$
