30 : 6 = 5; 17 · 4 = 68; 51 : 9 = 5 ост. 6; 13 + 52 = 65.

24 + 33 = 57; 64 : 9 = 7 ост. 1; 100 : 5 = 20; 70 − 62 = 8.

83 − 48 = 35; 93 − 34 = 59; 3 · 20 = 60; 56 : 7 = 8.

32 : 8 = 4; 48 : 16 = 3; 15 · 5 = 75; 83 − 18 = 65.

90 − 61 = 29; 12 · 8 = 96; 14 : 5 = 2 ост. 4; 37 : 4 = 9 ост. 1.

28 + 51 = 79; 63 : 7 = 9; 42 : 3 = 14; 24 · 3 = 72.
