So I know that |-5| = 5 but what does this - |-5| equal? and explain why

Absolute value

means whatever is inside is positive, once we resolve the inside, work out

|-5|=5

now - 5=?=-5

answer is - 5 since - of + is negaitve

if you don't get it still think like this

|-5|=5

mulitp; ly by - 1 everybody

-|-5|=-5
