Solve 5*(-6)div2+(4-7)^3/2*(-1)

$$\frac { 5 \cdot ( - 6 ) \div 2 + ( 4 - 7 ) ^ { 3 } } { 2 \cdot ( - 1 ) }$$

Evaluate

$$21$$

Solution Steps

Multiply 5 and -6 to get -30.

$$\frac{\frac{-30}{2}+\left(4-7\right)^{3}}{2\left(-1\right)}$$

Divide -30 by 2 to get -15.

$$\frac{-15+\left(4-7\right)^{3}}{2\left(-1\right)}$$

Subtract 7 from 4 to get -3.

$$\frac{-15+\left(-3\right)^{3}}{2\left(-1\right)}$$

Calculate -3 to the power of 3 and get -27.

$$\frac{-15-27}{2\left(-1\right)}$$

Subtract 27 from -15 to get -42.

$$\frac{-42}{2\left(-1\right)}$$

Multiply 2 and -1 to get -2.

$$\frac{-42}{-2}$$

Divide -42 by -2 to get 21.

$$21$$

Factor

$$3\times 7$$
