@talha_5600@Hoor9234 None of those numbers cancel each other out
The equation is 9-9Γ9+9 not -9+9Γ9+9
9-9Γ9+9
9Γ9=81 yes but if helps keep the equation together look at it as
-(9Γ9)= -81
9-81+9 and if that still confuses you simplify the 2 positive numbers
9+9= 18
18-81=
@sqsehrish@Hoor9234 9-9Γ9+9β 81
multiply first which I believe you did
9-9Γ9+9
9Γ9=81
9-81+9=
where I think you got confused is you saw 9 on both sides of 81 and thought one 9 was positive and the other was negative so they cancel out but they are both positive the 81 however is negative.
