(a+1-b+3) would equal just like (a-b+3+1)=(a-b+4). therefore (a+1+b-3)=(a+b+1-3)=(a+b-2)

Solution
* To find out if they are equal, you must subtract them, and if the answer is 0 tthen they are equal
1. (a+1-b+3) - (a-b+4) = 0
a+1-b+3 -a +b -4 = 0 *spead the negative
*now they all cancel out! So that means they are equal!
2. (a+1+b-3) - (a+b+2) = 0
a+1+b-3 -a -b -2 = 0 *spread the negative
* 'a' will cancel
'b' will cancel
1-3-2 is left and becomes -4
-4 = 0 *-4 is not 0 so..
therefore..unequal
there you have it

yes the first one equals but the second one doesn't. just think of the letters as numbers when trying to figure out these sort of problems
ex - 5+1-5+3+=4 ~ 5-5+4=4
ex - 4+1+4-3=6 ~ 4+4+2=10

yes for the first one and no for the second. (a+1+b-3) equals (a+b-2)
