$$19 \div 19 \times 0-2+5 \times 60 \div 15(-20+15 \div 5 \times 17 \times 0-2 \div 2+1)-2 \times 5 \div 5 \times 0$$

Evaluate

$$-402$$

Solution Steps

Divide 19 by 19 to get 1.

$$1\times 0-2+\frac{5\times 60}{15}\left(-20+\frac{15}{5}\times 17\times 0-\frac{2}{2}+1\right)-\frac{2\times 5}{5}\times 0$$

Divide 2 by 2 to get 1.

$$1\times 0-2+\frac{5\times 60}{15}\left(-20+\frac{15}{5}\times 17\times 0-1+1\right)-\frac{2\times 5}{5}\times 0$$

Multiply 1 and 0 to get 0.

$$0-2+\frac{5\times 60}{15}\left(-20+\frac{15}{5}\times 17\times 0-1+1\right)-\frac{2\times 5}{5}\times 0$$

Subtract 2 from 0 to get -2.

$$-2+\frac{5\times 60}{15}\left(-20+\frac{15}{5}\times 17\times 0-1+1\right)-\frac{2\times 5}{5}\times 0$$

Multiply 5 and 60 to get 300.

$$-2+\frac{300}{15}\left(-20+\frac{15}{5}\times 17\times 0-1+1\right)-\frac{2\times 5}{5}\times 0$$

Divide 300 by 15 to get 20.

$$-2+20\left(-20+\frac{15}{5}\times 17\times 0-1+1\right)-\frac{2\times 5}{5}\times 0$$

Divide 15 by 5 to get 3.

$$-2+20\left(-20+3\times 17\times 0-1+1\right)-\frac{2\times 5}{5}\times 0$$

Multiply 3 and 17 to get 51.

$$-2+20\left(-20+51\times 0-1+1\right)-\frac{2\times 5}{5}\times 0$$

Multiply 51 and 0 to get 0.

$$-2+20\left(-20+0-1+1\right)-\frac{2\times 5}{5}\times 0$$

Add -20 and 0 to get -20.

$$-2+20\left(-20-1+1\right)-\frac{2\times 5}{5}\times 0$$

Subtract 1 from -20 to get -21.

$$-2+20\left(-21+1\right)-\frac{2\times 5}{5}\times 0$$

Add -21 and 1 to get -20.

$$-2+20\left(-20\right)-\frac{2\times 5}{5}\times 0$$

Multiply 20 and -20 to get -400.

$$-2-400-\frac{2\times 5}{5}\times 0$$

Subtract 400 from -2 to get -402.

$$-402-\frac{2\times 5}{5}\times 0$$

Cancel out 5 and 5.

$$-402-2\times 0$$

Multiply 2 and 0 to get 0.

$$-402-0$$

Subtract 0 from -402 to get -402.

$$-402$$

Factor

$$-402$$
