Steps to Solve

1. Evaluate each expression individually

   Start by solving each mathematical expression step by step.

2. Calculate 8 - 79

   This is a simple subtraction:

   $$ 8 - 79 = -71 $$

3. Calculate -19 + (-17)

   This involves adding two negative numbers:

   $$ -19 + (-17) = -36 $$

4. Calculate 39 + (-6)

   This is adding a negative number:

   $$ 39 - 6 = 33 $$

5. Calculate -543 + 217

   Subtract the smaller number from the larger one:

   $$ -543 + 217 = -326 $$

6. Calculate 14 + (-42)

   Again, this is adding a negative number:

   $$ 14 - 42 = -28 $$

7. Calculate 11 - 46

   This involves subtraction:

   $$ 11 - 46 = -35 $$

8. Evaluate -a + -b if a = -312 and b = 405

   Substitute the values of a and b:

   $$ -(-312) - 405 = 312 - 405 = -93 $$

9. Evaluate -x - y if x = 7 and y = -31

   Substitute the values for x and y:

   $$ -7 - (-31) = -7 + 31 = 24 $$

10. Calculate |47 + (-58)| - 71

    First, compute inside the absolute value:

    $$ |47 - 58| = |-11| = 11 $$

Then perform the subtraction:

$$ 11 - 71 = -60 $$

11. Calculate -|17 - (-62)|

    First, resolve inside the absolute value:

    $$ 17 + 62 = 79 $$

Then apply the negative:

$$ -|79| = -79 $$
