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?

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

 

Sure, one again you nailed it.

 

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,
