Solution steps

(1) + (1) (1) + (3) (- 1)

Follow the PEMDAS order of operations

Multiply and divide (left to right)

(1) (1) : 1

(1) (1)

Apply rule:

(a) = a

(1) = 1

= 1 \cdot 1

Multiply the numbers:

1 \cdot 1 = 1

= 1

= (1) + 1 + (3) (- 1)

Multiply and divide (left to right)

(3) (- 1) : - 3

(3) (- 1)

Apply rule

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

(3) (- 1) = - 3 \cdot 1 = - 3

= - 3

= (1) + 1 - 3

Add and subtract (left to right)

(1) + 1 - 3 : - 1

(1) + 1 - 3

(1) + 1 = 2

= 2 - 3

2 - 3 = - 1

= - 1

= - 1

\frac{1}{2} \cdot 0 + 2

2 (0) + 7

24 \times 9 \times 3 \div 6

(5 - 4) (2 + (7 - 4) - (5 - 2) 4 + 7 (5 + 1))

(- 2) + 4 + (- 6) + 8
