35:5+36:4-3= 100-27:3*6+7*4= 80-6*5-18:3*5= 60-45:5*4+2*5= 48:6+19-2*6= 9*4-18+7*7-3*5=

Первый пример.

35 : 5 + 36 : 4 - 3 = 13;

35 / 5 = 7;

36 / 4 = 9;

9 - 3 = 6;

7 + 6 = 13.

Второй пример.

100 - 27 : 3 * 6 + 7 * 4 = 74;

27 / 3 = 9;

9 * 6 = 54;

100 - 54 = 46;

7 * 4 = 28;

46 + 28 = 74.

Третий пример.

80 - 6 * 5 - 18 : 3 * 5 = 20;

6 * 5 = 30;

80 - 30 = 50;

18 / 3 = 6;

6 * 5 = 30;

50 - 30 = 20;

Четвертый пример.

60 - 45 : 5 * 4 + 2 * 5 = 34;

45 / 5 = 9;

9 * 4 = 36;

60 - 36 = 24;

2 * 5 = 10;

24 + 10 = 34.

Пятый пример.

48 : 6 + 19 - 2 * 6 = 15;

48 / 6 = 8;

2 * 6 = 12;

19 - 12 = 7;

8 + 7 = 15.

Шестой пример.

9 * 4 - 18 + 7 * 7 - 3 * 5 = 52;

9 * 4 = 36;

36 - 18 = 18;

7 * 7 = 49;

18 + 49 = 67;

3 * 5 = 15;

67 - 15 = 52.
