Comment on Some Squared vs All Squared
I also would like to add
Quantity A: (x-y)(x+y) Quantity B:(x-y)(x-y)
We can cancel one (x-y) from both sides.
Quantity A:(x+y) Quantity B:(x-y)
Quantity A therefore: 999.9 Quantity B: 1000
So, Quantity B is greater.
P.S. Your lessons are great :)
That's a great approach!
