Solve 36-100div10*2div20+50div2+7*3

$$36 - 100 \div 10 \times 2 \div 20 + 50 \div 2 + 7 \times 3$$

Evaluate

$$81$$

Solution Steps

Divide 100 by 10 to get 10.

$$36-\frac{10\times 2}{20}+\frac{50}{2}+7\times 3$$

Multiply 10 and 2 to get 20.

$$36-\frac{20}{20}+\frac{50}{2}+7\times 3$$

Divide 20 by 20 to get 1.

$$36-1+\frac{50}{2}+7\times 3$$

Subtract 1 from 36 to get 35.

$$35+\frac{50}{2}+7\times 3$$

Divide 50 by 2 to get 25.

$$35+25+7\times 3$$

Add 35 and 25 to get 60.

$$60+7\times 3$$

Multiply 7 and 3 to get 21.

$$60+21$$

Add 60 and 21 to get 81.

$$81$$

Factor

$$3^{4}$$
