Evaluate

$$18$$

Solution Steps

Subtract 4 from 15 to get 11.

$$11+3-\left(12-5\times 2\right)+5+\frac{16}{4}-5+10-2^{3}$$

Add 11 and 3 to get 14.

$$14-\left(12-5\times 2\right)+5+\frac{16}{4}-5+10-2^{3}$$

Multiply 5 and 2 to get 10.

$$14-\left(12-10\right)+5+\frac{16}{4}-5+10-2^{3}$$

Subtract 10 from 12 to get 2.

$$14-2+5+\frac{16}{4}-5+10-2^{3}$$

Subtract 2 from 14 to get 12.

$$12+5+\frac{16}{4}-5+10-2^{3}$$

Add 12 and 5 to get 17.

$$17+\frac{16}{4}-5+10-2^{3}$$

Divide 16 by 4 to get 4.

$$17+4-5+10-2^{3}$$

Add 17 and 4 to get 21.

$$21-5+10-2^{3}$$

Subtract 5 from 21 to get 16.

$$16+10-2^{3}$$

Calculate 2 to the power of 3 and get 8.

$$16+10-8$$

Subtract 8 from 10 to get 2.

$$16+2$$

Add 16 and 2 to get 18.

$$18$$

Factor

$$2\times 3^{2}$$
