Can someone explain to me how to calculate the following:
| -3 - | -7-7||.

  • Math -

    The '|' signs are absolute value - the results are always positive.

    Calculate the inner '|' first, as you would parentheses.

    |-3-|-7-7||
    = |-3-|-14||
    = |-3-14| because |-14| = the absolute value of -14 = 14
    = |-17|
    = 17
