Solve (-8)+(-3)*(+18)-9div(-2)

$$(-8)+(-3) \times (+18)-9 \div (-2)$$

Evaluate

$$-\frac{115}{2}=-57.5$$

Solution Steps

Multiply -3 and 18 to get -54.

$$-8-54-\frac{9}{-2}$$

Subtract 54 from -8 to get -62.

$$-62-\frac{9}{-2}$$

Fraction \frac{9}{-2} can be rewritten as -\frac{9}{2} by extracting the negative sign.

$$-62-\left(-\frac{9}{2}\right)$$

The opposite of -\frac{9}{2} is \frac{9}{2}.

$$-62+\frac{9}{2}$$

Convert -62 to fraction -\frac{124}{2}.

$$-\frac{124}{2}+\frac{9}{2}$$

Since -\frac{124}{2} and \frac{9}{2} have the same denominator, add them by adding their numerators.

$$\frac{-124+9}{2}$$

Add -124 and 9 to get -115.

$$-\frac{115}{2}$$

Factor

$$-\frac{115}{2} = -57\frac{1}{2} = -57.5$$
