10 + |-2| =

Is the | sign the same as a ( ?

The full question is:

| 10 - 2| < 10 + | -2 |
True or false ?

if | = ( then it's false, but I vaguely remember something about absolute. If it makes the -2 into 2 then the equation is true. What do you think ???

|a| represents the absolute value of a.
So in this case:
|10 - 2| < 10 + |-2| = 8 < 12 is true
