Solve (-2)+[{13+(-6*1)}]div(-20)=

$$( - 2 ) + [ \{ 13 + ( - 6 \times 1 ) \} ] \div ( - 20 ) =$$

Evaluate

$$-\frac{47}{20}=-2.35$$

Solution Steps

Multiply -6 and 1 to get -6.

$$-2+\frac{13-6}{-20}$$

Subtract 6 from 13 to get 7.

$$-2+\frac{7}{-20}$$

Fraction \frac{7}{-20} can be rewritten as -\frac{7}{20} by extracting the negative sign.

$$-2-\frac{7}{20}$$

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

$$-\frac{40}{20}-\frac{7}{20}$$

Since -\frac{40}{20} and \frac{7}{20} have the same denominator, subtract them by subtracting their numerators.

$$\frac{-40-7}{20}$$

Subtract 7 from -40 to get -47.

$$-\frac{47}{20}$$

Factor

$$-\frac{47}{20} = -2\frac{7}{20} = -2.35$$
