7 - 4 = 3

= 3

= 4 \cdot 3 + 5 (4 - 7) + 8

Calculate within parentheses

(4 - 7) : - 3

4 - 7

4 - 7 = - 3

= - 3

= 4 \cdot 3 + 5 (- 3) + 8

= - 3 + 8

- 3 + 8 = 5

= 5

= 5

\frac{1 - 2}{( \frac{2 - 3 \times 15 - 16}{- 4} ) - 2}

5 \times 8^{2} - 6 \times 7^{2} + 9 \times 2^{3}

2^{2} - 2 \times 2

25 + 4 + 7 - 10

\frac{192500}{( 20 - 50 ) ^{2}}
