13

Solution steps

2 (- 7) + 9 (3)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

2 (- 7) : - 14

2 (- 7)

Apply rule

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

2 (- 7) = - 2 \cdot 7 = - 14

= - 14

= - 14 + 9 (3)

Multiply and divide (left to right)

9 (3) : 27

9 (3)

Apply rule:

(a) = a

(3) = 3

= 9 \cdot 3

Multiply the numbers:

9 \cdot 3 = 27

= 27

= - 14 + 27

Add and subtract (left to right)

- 14 + 27 : 13

- 14 + 27

- 14 + 27 = 13

= 13

= 13

45 - 13 + (56 - 32) + (48 - 36) - 26

- 2 (- 8) + 7

\frac{( - 6 \times 2 )}{- 3}

(- 1)^{2} + 4 (- 1) + 6

9 - 11 [2 - (2^{2} + 11)]
