Evaluate

$$25$$

Solution Steps

Calculate 2 to the power of 3 and get 8.

$$8+\frac{10}{2}+5\times 3+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Divide 10 by 2 to get 5.

$$8+5+5\times 3+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Add 8 and 5 to get 13.

$$13+5\times 3+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Multiply 5 and 3 to get 15.

$$13+15+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Add 13 and 15 to get 28.

$$28+4-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Add 28 and 4 to get 32.

$$32-5\times 2-8+4\times 2^{2}-\frac{20}{4}$$

Multiply 5 and 2 to get 10.

$$32-10-8+4\times 2^{2}-\frac{20}{4}$$

Subtract 10 from 32 to get 22.

$$22-8+4\times 2^{2}-\frac{20}{4}$$

Subtract 8 from 22 to get 14.

$$14+4\times 2^{2}-\frac{20}{4}$$

Calculate 2 to the power of 2 and get 4.

$$14+4\times 4-\frac{20}{4}$$

Multiply 4 and 4 to get 16.

$$14+16-\frac{20}{4}$$

Add 14 and 16 to get 30.

$$30-\frac{20}{4}$$

Divide 20 by 4 to get 5.

$$30-5$$

Subtract 5 from 30 to get 25.

$$25$$

Factor

$$5^{2}$$
