Estimate the answer and say if it will be more or less than 100. Match with the correct one. 134 – 56, 20 + 41, 150 – 49, 199 – 90, 70 + 30 + 1, 156 – 65, 68 – 26, 95 + 10 + 5, 109 – 80, 63 + 26, 124 + 23 + 20

Correct Answer

More than 100: 150 – 49 = 101, 199 – 90 = 109, 70 + 30 + 1 = 101, 95 + 10 + 5 = 110, 124 + 23 + 20 = 167. Less than 100: 134 – 56 = 78, 20 + 41 = 61, 156 – 65 = 91, 68 – 26 = 42, 109 – 80 = 29, 63 + 26 = 89.
