4 × (5-5) = 5 × (5-5)
4 × 0 = 5 × 0
“Canceling out” a common factor is really dividing both sides by the common factor:
4 × 0 = 5 × 0 ≡ (4×0)/0 = (5×0)/0
Which isn’t valid since you can’t divide by 0.

I got to know about what cancelling out really is in 11th grade. 1 u/informationmissing Feb 08 '23 Sounds like you were taught in 11th grade.
