Solve 4*5-(-6)div4

$$4 \times 5-(-6) \div 4$$

Evaluate

$$\frac{43}{2}=21.5$$

Solution Steps

Multiply 4 and 5 to get 20.

$$20-\frac{-6}{4}$$

Reduce the fraction \frac{-6}{4} to lowest terms by extracting and canceling out 2.

$$20-\left(-\frac{3}{2}\right)$$

The opposite of -\frac{3}{2} is \frac{3}{2}.

$$20+\frac{3}{2}$$

Convert 20 to fraction \frac{40}{2}.

$$\frac{40}{2}+\frac{3}{2}$$

Since \frac{40}{2} and \frac{3}{2} have the same denominator, add them by adding their numerators.

$$\frac{40+3}{2}$$

Add 40 and 3 to get 43.

$$\frac{43}{2}$$

Factor

$$\frac{43}{2} = 21\frac{1}{2} = 21.5$$
