Question

evaluate -|-618|

please help me, I just don't get it

Answer 1

let n = any real integer.
the absolute value of n, or | n | , means you always get its positive value. for example,
| 2 | = 2
|-5 | = 5
| 0 | = 0
thus for -|-618| , we first get its absolute value, then multiply by -1 :
-|-618| = -(618) = -618

hope this helps~ :)
