Question

$$30 - [ 11 + \{ 18 - ( 48 \div 8 \times 2 ) \} + 7 ] + 15$$

Evaluate

$21$

Solution Steps

Divide $48$ by $8$ to get $6$.

$$30-\left(11+18-6\times 2+7\right)+15$$

Multiply $6$ and $2$ to get $12$.

$$30-\left(11+18-12+7\right)+15$$

Subtract $12$ from $18$ to get $6$.

$$30-\left(11+6+7\right)+15$$

Add $11$ and $6$ to get $17$.

$$30-\left(17+7\right)+15$$

Add $17$ and $7$ to get $24$.

$$30-24+15$$

Subtract $24$ from $30$ to get $6$.

$$6+15$$

Add $6$ and $15$ to get $21$.

$$21$$

Factor

$3\times 7$
