= 1

= - 2 \cdot 1 - 3 (1) - 1

Multiply and divide (left to right)

- 2 \cdot 1 : - 2

- 2 \cdot 1

- 2 \cdot 1 = - 2

= - 2

= - 2 - 3 (1) - 1

Multiply and divide (left to right)

3 (1) : 3

3 (1)

Apply rule:

(a) = a

(1) = 1

= 3 \cdot 1

Multiply the numbers:

= - 6

= - 6

6^{2} + 1^{2}

5 \cdot 3^{5}

- (7 - 5 + 4)

6 \frac{3}{4} + (4 \frac{2}{4} + 5 \frac{1}{4})

\frac{2}{27} (3^{7} - 8 \cdot 7 + 2)
