Answer 3

Calculation 1: 3.5 - (+7)

To calculate 3.5 - (+7), we can simplify the expression by removing the parentheses around the positive 7. This gives us:

3.5 - 7

Subtracting 7 from 3.5 gives us the result:

-3.5

Calculation 2: 3.6 - (-5)

To calculate 3.6 - (-5), we can simplify the expression by changing the double negative (-5) to a positive 5. This gives us:

3.6 + 5

Adding 5 to 3.6 gives us the result:

8.6

Calculation 3: 4.6 - (+2.5)

To calculate 4.6 - (+2.5), we can simplify the expression by removing the parentheses around the positive 2.5. This gives us:

4.6 - 2.5

Subtracting 2.5 from 4.6 gives us the result:

2.1

Calculation 4: -8 - (-1/7)

To calculate -8 - (-1/7), we can simplify the expression by changing the double negative (-1/7) to a positive 1/7. This gives us:

-8 + 1/7

Adding 1/7 to -8 gives us the result:

-55/7

Calculation 5: 1/6 - (+3)

To calculate 1/6 - (+3), we can simplify the expression by removing the parentheses around the positive 3. This gives us:

1/6 - 3

Subtracting 3 from 1/6 gives us the result:

-17/6

Calculation 6: -5/12 - (-4)

To calculate -5/12 - (-4), we can simplify the expression by changing the double negative (-4) to a positive 4. This gives us:

-5/12 + 4

Adding 4 to -5/12 gives us the result:

43/12
