    Hello,

    I really don't know what title should I use. But please,help me indicate my answer whether it is correct or wrong. Okay?:p

    1) -|12| (+12) = -144

    2) |8| + (+12) = +20

    3) |24| - (+23) = +1

    Also guys, what program do you use when creating mathematics formula?;)

    THANKS

    They all seem good to me.
    Here are some more examples:
    |-12|(+12)=144
    8-|-12|=-4
    24-|-23|=1

    I write my essays in MS Word usually and I use its extension named Mathtype that produces images of formulas written in Latex. This site also uses Latex as its equation editor.

    Thank you very much, Georacer.

    How about this

    -|-12| + |-24| = +12

    Am I correct? Thanks again

    It's easier if you use the asterisk to show multiplication, or even a lowercase x. The way the absolute (| |) works is after any evaluation within the | and | is done, just drop the sign. Any signs outside the marks remain.

    -|1+2-4| x |2| = -|-1| x 2 = - 1 x 2 = -2

    The "-" in "- 1 x 2" is the minus sign OUTSIDE the Absolute marks.

    Hope this helps,
