Question

 90-73+8          93-(46+9)34+36-984-58-7        (28+33)-8 54-(42-7)   

Answer 1

90-73+8=25 . 93-(46+9)= 38 34+36-9=61 84-58-7=19 (28+33)-8=52 54-(42-7)= 18

Answer 2

90-73+8=19
93-(46+9)48
34+36-7=61
84-58-7=33
(28+33)-8=53
54-(42-7)=9

Answer 3

Let's calculate each expression step by step:

1. 90 - 73 + 8: First, subtract 73 from 90: 90 - 73 = 17. Then, add 8 to 17: 17 + 8 = 25. Therefore, the result is 25.

2. 93 - (46 + 9) * 34 + 36 - 984 - 58 - 7: First, calculate the expression inside the parentheses: 46 + 9 = 55. Then, multiply 55 by 34: 55 * 34 = 1870. Next, subtract 1870 from 93: 93 - 1870 = -1777. Finally, subtract 984, 58, and 7 from -1777: -1777 - 984 - 58 - 7 = -2826. Therefore, the result is -2826.

3. (28 + 33) - 8 * 54 - (42 - 7): First, calculate the expression inside the parentheses: 28 + 33 = 61 and 42 - 7 = 35. Then, multiply 8 by 54: 8 * 54 = 432. Next, subtract 432 from 61: 61 - 432 = -371. Finally, subtract 35 from -371: -371 - 35 = -406. Therefore, the result is -406.

The calculated results for each expression are as follows:

1. 90 - 73 + 8 = 25
2. 93 - (46 + 9) * 34 + 36 - 984 - 58 - 7 = -2826
3. (28 + 33) - 8 * 54 - (42 - 7) = -406
