Solve -70*2+4+2/8-4

$$- 70 * 2 + 4 + 2 / 8 - 4$$

Evaluate

$$-\frac{559}{4}=-139.75$$

Solution Steps

Multiply -70 and 2 to get -140.

$$-140+4+\frac{2}{8}-4$$

Add -140 and 4 to get -136.

$$-136+\frac{2}{8}-4$$

Reduce the fraction \frac{2}{8} to lowest terms by extracting and canceling out 2.

$$-136+\frac{1}{4}-4$$

Convert -136 to fraction -\frac{544}{4}.

$$-\frac{544}{4}+\frac{1}{4}-4$$

Since -\frac{544}{4} and \frac{1}{4} have the same denominator, add them by adding their numerators.

$$\frac{-544+1}{4}-4$$

Add -544 and 1 to get -543.

$$-\frac{543}{4}-4$$

Convert 4 to fraction \frac{16}{4}.

$$-\frac{543}{4}-\frac{16}{4}$$

Since -\frac{543}{4} and \frac{16}{4} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-543-16}{4}$$

Subtract 16 from -543 to get -559.

$$-\frac{559}{4}$$

Factor

$$-\frac{559}{4} = -139\frac{3}{4} = -139.75$$
