(7 - 4) : 3

7 - 4

7 - 4 = 3

= 3

= 2 \cdot 3 + 3 (1 - 5) + 8

Calculate within parentheses

(1 - 5) : - 4

1 - 5

1 - 5 = - 4

= - 4

= 2 \cdot 3 + 3 (- 4) + 8

Multiply and divide (left to right)

2 \cdot 3 : 6

2 \cdot 3

2 \cdot 3 = 6

3 (- 4) = - 3 \cdot 4 = - 12

= - 12

= 6 - 12 + 8

Add and subtract (left to right)

6 - 12 + 8 : 2

6 - 12 + 8

6 - 12 = - 6

= - 6 + 8

- 6 + 8 = 2

= 2

= 2

11 \cdot 12

- 65 + \frac{6}{( - 3 )} + 40

4^{2} \cdot 2 - 30 \cdot \frac{2}{6} + 4 \cdot 3

\frac{900}{4}

8^{2} - \frac{16}{2 ^{2}} \cdot 4 - 3
