12 \cdot (- 3 + 4) - 5 \cdot (- 6)

42

Solution steps

12 (- 3 + 4) - 5 (- 6)

Follow the PEMDAS order of operations

Calculate within parentheses

(- 3 + 4) : 1

- 3 + 4

- 3 + 4 = 1

= 1

= 12 \cdot 1 - 5 (- 6)

Multiply and divide (left to right)

12 \cdot 1 : 12

12 \cdot 1

12 \cdot 1 = 12

= 12

= 12 - 5 (- 6)

Multiply and divide (left to right)

5 (- 6) : - 30

5 (- 6)

Apply rule

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

5 (- 6) = - 5 \cdot 6 = - 30

= - 30

= 12 - (- 30)

Add and subtract (left to right)

12 - (- 30) : 42

12 - (- 30)

Apply rule

- (- a) = + a

- (- 30) = + 30

= 12 + 30

12 + 30 = 42

= 42

= 42

5 \times 4 + 30 \div 6 - 35 \div 7

\frac{( 0 - 1 ) ^{4}}{4}

8 2^{2} - 1 8^{2}

4 (- 4)^{2} - (- 4)

4 (- 1) + 8
