36

Solution steps

5 (3) - 3 (- 7)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

5 (3) : 15

5 (3)

Apply rule:

(a) = a

(3) = 3

= 5 \cdot 3

Multiply the numbers:

5 \cdot 3 = 15

= 15

= 15 - 3 (- 7)

Multiply and divide (left to right)

3 (- 7) : - 21

3 (- 7)

Apply rule

a \cdot (- b) = - a \cdot b

3 (- 7) = - 3 \cdot 7 = - 21

= - 21

= 15 - (- 21)

Add and subtract (left to right)

15 - (- 21) : 36

15 - (- 21)

Apply rule

- (- a) = + a

- (- 21) = + 21

= 15 + 21

15 + 21 = 36

= 36

= 36

- 2 (3) - 3

6^{3} + 4

- 14 + (5 - (7 - 6) - (8 - 1 - 9) + 13)

\frac{1}{5} (- 5) - 3

(- 3) \times (6) + (- (- (18)))
