1) 13*7-69 +46+81:27*18+17= ? 2)29*3-49+27+19*4-59=? 3)72:18*23- 43+56:14+96=?

Answer 1

1) 139.
2) 82.
3) 149.

Answer 2

1) To solve the first expression, we can follow the order of operations (PEMDAS/BODMAS). Let's break it down step by step:

13 * 7 - 69 + 46 + 81 : 27 * 18 + 17

First, we perform the multiplication and division from left to right: 13 * 7 = 91 81 : 27 = 3

Now the expression becomes: 91 - 69 + 46 + 3 * 18 + 17

Next, we perform the multiplication: 3 * 18 = 54

Now the expression becomes: 91 - 69 + 46 + 54 + 17

Finally, we perform the addition and subtraction from left to right: 91 - 69 = 22 22 + 46 = 68 68 + 54 = 122 122 + 17 = 139

Therefore, the value of the first expression is 139.

2) Moving on to the second expression:

29 * 3 - 49 + 27 + 19 * 4 - 59

Again, we follow the order of operations:

29 * 3 = 87 19 * 4 = 76

Now the expression becomes: 87 - 49 + 27 + 76 - 59

Performing the addition and subtraction from left to right: 87 - 49 = 38 38 + 27 = 65 65 + 76 = 141 141 - 59 = 82

So, the value of the second expression is 82.

3) Lastly, let's solve the third expression:

72 : 18 * 23 - 43 + 56 : 14 + 96

Following the order of operations:

72 : 18 = 4 56 : 14 = 4

Now the expression becomes: 4 * 23 - 43 + 4 + 96

Performing the addition and subtraction from left to right: 4 * 23 = 92 92 - 43 = 49 49 + 4 = 53 53 + 96 = 149

Therefore, the value of the third expression is 149.

To summarize: 1) 13 * 7 - 69 + 46 + 81 : 27 * 18 + 17 = 139 2) 29 * 3 - 49 + 27 + 19 * 4 - 59 = 82 3) 72 : 18 * 23 - 43 + 56 : 14 + 96 = 149
