Evaluate: 24 / 3*2 ^ 2-2*7

Expression: $$24 \div 3 \cdot 2 ^ { 2 } - 2 \cdot 7$$

Divide $24$ by $3$ to get $8$.

$$8\times 2^{2}-2\times 7$$

Calculate $2$ to the power of $2$ and get $4$.

$$8\times 4-2\times 7$$

Multiply $8$ and $4$ to get $32$.

$$32-2\times 7$$

Multiply $2$ and $7$ to get $14$.

$$32-14$$

Subtract $14$ from $32$ to get $18$.

$$18$$
