8*4-32:4*2+15:3*4 = 4*4+21:3*4+50:1*6=

Первый пример.

8 * 4 - 32 : 4 * 2 + 15 : 3 * 4 = 36;

15 / 3 = 5;

5 * 4 = 20;

32 / 4 = 8;

8 * 2 = 16;

8 * 4 = 32;

32 - 16 = 16;

16 + 20 = 36;

Второй пример.

4 * 4 + 21 : 3 * 4 + 50 : 1 * 6 = 344;

50 / 1 = 50;

50 * 6 = 300;

21 / 3 = 7;

7 * 4 = 28;

4 * 4 = 16;

16 + 28 = 44;

44 + 300 = 344;
