So it's 9 -11 = 3?

Use a calculator 9 - 11 = -2

It seems like you have slight difficulties in addition/subtraction when the answer is negative...

\(\sf\large 9xy^2-11xy^2= xy^2(9-11)=xy^2(-2)=-2xy^2\)

just remember this, it will make it easier \(\sf\Large ab + ac = a(b+c)\)

Alright, i'll try to keep that in mind.

if you forget it, it's called the distributive property. and I just switched it so that it would be helpful for this question. The distributive property actually says: \(\sf\Large a(b+c) = ab+ac\)
