Answer 2

Calculation 1: 2 + 1 - 8 - 5 + 2

To calculate this expression, we can simply add and subtract the numbers in order:

2 + 1 - 8 - 5 + 2 = -8

Calculation 2: 15 divided by 7 + 3

To calculate this expression, we need to perform the division first and then add the result to 3:

15 divided by 7 = 2.142857142857143 (rounded to 15 decimal places)

2.142857142857143 + 3 = 5.142857142857143 (rounded to 15 decimal places)

So, 15 divided by 7 + 3 is approximately equal to 5.142857142857143.

Calculation 3: 0.6 - 2

To calculate this expression, we simply subtract 2 from 0.6:

0.6 - 2 = -1.4

Calculation 4: 99 + 33 + 1

To calculate this expression, we add the numbers together:

99 + 33 + 1 = 133

Calculation 5: 3 + 8 + 1 + 7 divided by 5 + 5 divided by 7 + 2 + 3 + 9 divided by 4 + 4 divided by 9

To calculate this expression, we need to perform the divisions first and then add all the numbers together:

7 divided by 5 = 1.4 (rounded to 1 decimal place)

5 divided by 7 = 0.7142857142857143 (rounded to 15 decimal places)

9 divided by 4 = 2.25

4 divided by 9 = 0.4444444444444444 (rounded to 15 decimal places)

Now, let's add all the numbers together:

3 + 8 + 1 + 1.4 + 0.7142857142857143 + 2 + 3 + 2.25 + 0.4444444444444444 = 21.80873015873016 (rounded to 15 decimal places)

So, the result of the expression is approximately equal to 21.80873015873016.
