its \(||-4|-|-9||\) right ? there is no 1 in that...

OpenStudy (anonymous):

no 1's

hartnn (hartnn):

remember, that if \(|-a| =a\) if a is positive

OpenStudy (xapproachesinfinity):

OpenStudy (anonymous):

my bad i should have wrote it better

hartnn (hartnn):

so, for example \(|-100| = 100, |6|=6, |-81| =81 \) and so on in short, answer to |..| can never be negative

hartnn (hartnn):
