Guys quickly #finals answer all of the steps i'm offering 15pts (which is more than what its worth) and brainliest answer

Ais greater than 0 so it's a postivite number
b is less than 0 is a nenative number

in case a
-a + b = negative
a was positive but because on the negative sign in front on it, it now becomes negative. a negative number plus a negative number is equal to a negative number.

in case b
a-b = positive
a positive number minus a negative number is equal to positive.

in case b
b-a = negative
a negative number minus a negative number is equal to a negative number. [putting a minus in front of a positive number automatic becomes negative]

can i get the brainlest
