Answer 4

only negatives ll remove?

Answer 5

I like doing it like this, it's more fun:\[4+4-4+4\]\[4+4\cancel{-4}\cancel{+4}\]\[4+4=8\]

Answer 6

Absolute value is thinking in terms of magnitude. If I drew arrows from 0 to both -4 and 4 on a number line, each arrow has a magnitude of 4, but one has a positive direction (to the right) and the other negative (to the left). So, absolute value is just asking for magnitude.

Answer 7

therefore \[|-4| = |4| = 4\]
