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
