Solution steps

1 - (- 8) - \frac{12}{- 3}

Simplify

\frac{12}{- 3} : - 4

Apply the fraction rule:

\frac{a}{- b} = - \frac{a}{b}

= - \frac{12}{3}

Divide the numbers:

Follow the PEMDAS order of operations

Add and subtract (left to right)

1 - (- 8) - (- 4) : 13

1 - (- 8) - (- 4)

Apply rule

- (- a) = + a

- (- 8) = + 8

= 1 + 8 - (- 4)

Apply rule

- (- a) = + a

- (- 4) = + 4

= 9 + 4

9 + 4 = 13

= 13

= 13

1/2 + 3/5 + 1/4

1 \times 1 + 2 \times (- \frac{1}{2}) + 3 \times 0

25 + 100 + (- 19) + (- 11) + 18

- 2^{2} + 8 (- 2) + 12

1/2 + (2) - 1/5
