Solve 9div(-3)(-2)+1-6-7(-3)*5div5-20:(-10)(-1)

$$9 \div ( - 3 ) ( - 2 ) + 1 - 6 - 7 ( - 3 ) \times 5 \div 5 - 20 : ( - 10 ) ( - 1 )$$

Evaluate

$$20$$

Solution Steps

Divide 9 by -3 to get -3.

$$-3\left(-2\right)+1-6-\frac{7\left(-3\right)\times 5}{5}-\frac{20}{-10}\left(-1\right)$$

Multiply -3 and -2 to get 6.

$$6+1-6-\frac{7\left(-3\right)\times 5}{5}-\frac{20}{-10}\left(-1\right)$$

Add 6 and 1 to get 7.

$$7-6-\frac{7\left(-3\right)\times 5}{5}-\frac{20}{-10}\left(-1\right)$$

Subtract 6 from 7 to get 1.

$$1-\frac{7\left(-3\right)\times 5}{5}-\frac{20}{-10}\left(-1\right)$$

Cancel out 5 and 5.

$$1-7\left(-3\right)-\frac{20}{-10}\left(-1\right)$$

Multiply 7 and -3 to get -21.

$$1-\left(-21\right)-\frac{20}{-10}\left(-1\right)$$

The opposite of -21 is 21.

$$1+21-\frac{20}{-10}\left(-1\right)$$

Add 1 and 21 to get 22.

$$22-\frac{20}{-10}\left(-1\right)$$

Divide 20 by -10 to get -2.

$$22-\left(-2\left(-1\right)\right)$$

Multiply -2 and -1 to get 2.

$$22-2$$

Subtract 2 from 22 to get 20.

$$20$$

Factor

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