a) i think its but not sure \[a+(-b)\] b)in a number line the interval \[[b,a]\] should include numbers btn a and b, so that you can count them and determine the difference btn a and b c) you determine the sign by noting what number is larger btn a and b, if b is larger then the result wil be negative, otherwise it'll be positive
Thank you thank you so so much
are you 100 % sure on these except for the first one?
and for b should I Make a number line?
@pkjag you there?
make a number line where a is larger than b n just put some random distance btn them
can you show me exactly please sorry if im asking for to much i just really need this
@pkjag you there?
