3 \cdot 4 : 12

3 \cdot 4

3 \cdot 4 = 12

= 12

= 12 - 5 (2) + 2

Multiply and divide (left to right)

5 (2) : 10

5 (2)

Apply rule:

(a) = a

(2) = 2

= 5 \cdot 2

Multiply the numbers:

= 2 + 2

2 + 2 = 4

= 4

= 4

27 + 6 \times 5 - 32 \div 2 - 41

- (- 1)^{2} - 2 (- 1) + 3

- (- 1)^{2} - 2 (- 1) - 2

76 + (- 17) + (- 25) + 4

104 + 22 \times 36 - 225 \div 25 - 15 \times 5 + 5
