so first, simplify the signs so they don’t confuse you,

-5/6 - 17/18 + 2/9 (Since there are two negatives near the end, and their tecxhnically being mulitplied, -2/9*-1 (I added 1 for place holder) and when you multiply a negatives by a negative, you get a positive.

So find the lcm of the denominators which is 18 in this case

-15/18 - 17/18 + 4/18

Now solve the problem from left to right

you’ll get -1 5/9 if you simplified

-1 5/9 that’s he difference xx welcome
