Solve (12+16+20)*15+22*(20*16/2)

$$(12+16+20) \times 15+22 \times ( \frac{ 20 \times 16 }{ 2 } )$$

Evaluate

$$4240$$

Solution Steps

Add 12 and 16 to get 28.

$$\left(28+20\right)\times 15+22\times \frac{20\times 16}{2}$$

Add 28 and 20 to get 48.

$$48\times 15+22\times \frac{20\times 16}{2}$$

Multiply 48 and 15 to get 720.

$$720+22\times \frac{20\times 16}{2}$$

Multiply 20 and 16 to get 320.

$$720+22\times \frac{320}{2}$$

Divide 320 by 2 to get 160.

$$720+22\times 160$$

Multiply 22 and 160 to get 3520.

$$720+3520$$

Add 720 and 3520 to get 4240.

$$4240$$

Factor

$$2^{4}\times 5\times 53$$
