    The answer to that is 10

    a+b+c is equal to 4+-2+8

    4+-2 is the same as 4-2, which is 2.

    2 + 8 equals 10. That is your question.

    Replace the variables to what they are equal to.

    4 + (-2) + 8

    Now add them up.

    4 + (-2) + 8 = 2 + 8 = 10

    So, 10 is the answer to this question.
