37 - 20 ni hisoblash usulini toping
37 – 20 = (30 + 7) – 20 = (30 – 20) + 7 = 10 + 7 = 17;
37 – 20 = (30 - 7) – 20 = (30 – 20) -7 = 10 + 7 = 17;
37 – 20 = (37 - 7) – 20 = (30 – 20) + 7 = -10 - 7 = 17;
37 – 20 = (30 - 7) + 20 = (30 – 20) - 7 = -10 + 7 = 17;

37 – 2 ni hisoblash usulini toping.
37 – 2 = (30 + 7) – 2 = 30 - (7 – 2) = 30 - 5 = 35;
37 – 2 = (30 + 7) – 2 = 30 + (7 – 2) = 30 + 5 = 35;
37 – 2 = (37 - 7) – 2 = 30 + (7 – 2) = -30 + 5 = 35;
37 – 2 = (30 - 7) + 2 = 30 + (7 – 2) = -30 - 5 = 35;

25 + 17 ni hisoblash usulini toping.
25 + 17 = (22 + 3) + 17 = 22 + (3 + 17) = 22 + 20 = 42;
25 + 17 = (20 + 5) + 10+7 = (20 + 17) - 5 = 37 + 5 = (37 + 3) + 2 = 42;
25 + 17 = 20+5 - (5 + 12) = (25 + 5) - 12 = 30 + 12 = 42;
25 + 17 = (20 + 5) - (10 + 7) = (20 + 10) - (5 + 7) = 30 + 12 = 42;

42 - 5 ni hisoblash usulini toping
42 – 5 = 42 – 2 – 3 = (42 – 2) – 3 = 40 – 3 = 37;
42 – 5 = 40 + 2 – 3 = (42 + 2) – 3 = 44 – 3 = 37;
42 – 5 = 40 – 2 – 3 = (42 – 2) – 3 = - 40 – 3 = 37;
42 – 5 = 40 – 2 + 3 = (42 – 2) + 3 = 40 + 3 = 37;

38 + 5 ni hisoblash usulini toping.
38 + 5 = 38 + 2 + 3 = (38 + 2) + 3 = 40 + 3 = 43;
38 + 5 = 40 - 2 + 3 = (38 - 2) - 3 = 36 + 3 = 43;
38 + 5 = 38 - 2 - 3 = (38 + 2) - 2+1 = 40 + 1 = 43;
38 + 5 = 38 + 2 + 3 = (38 - 2) - 3 = - 40 - 3 = 43;
