Question

(41+253)-67= 45×(28+7)-8= (64+36)+15:5×7= 904-(348-264)-57= (904-348)-(264-157)=

Answer 1

1)227
2)1567
3)121
4)763
5)449

Answer 2

Let's solve each of these equations step by step:

1. (41 + 253) - 67 = 294 - 67 = 227

2. 45 × (28 + 7) - 8 = 45 × 35 - 8 = 1575 - 8 = 1567

3. (64 + 36) + 15 ÷ 5 × 7 = 100 + 3 × 7 = 100 + 21 = 121

4. 904 - (348 - 264) - 57 = 904 - 84 - 57 = 820 - 57 = 763

5. (904 - 348) - (264 - 157) = 556 - 107 = 449

So, the results of each equation are:

1. 227
2. 1567
3. 121
4. 763
5. 449
