Counting Number of Squares - Complete Video

[@karenf.sanders7559]

This is a good lesson. However, if you had used colored pens when changing squares and/or shading, it would have made it clearer.

[@khuviloumikrii3277]

Whoever watch the first Video will fall in love with This..Well explain Thank you sir

[@archidar1]

Intuition for why the sum of squares works:
n^2 = number of 1x1 squares that can be counted
(n-1)^2 = number of 2x2 squares that can be counted. Visually, just think of this as removing the top row and right column, then treat each remaining square as the bottom-left square of your 2x2 grid. Then since every square in the (n-1)^2 grid represents the bottom-left of every 2x2 possible, there must be (n-1)^2 such 2x2 squares possible.
Same thing for (n-2)^2 and onwards, just remove the next top row, the next right column, treat every remaining square as the bottom-left of a 3x3 grid.
This applies to the rectangle case as well.

Respected Sir,
I have a query regarding the figure in which you counted 30 squares.
you calculated
4*4=16
3*3=9
2*2=4
1*1=1
total stands 30
now my query is that if we hide all 30 squares then in the last 1 more big square remains. This big square which contents all 30 squares.
but in counting whether we should not add big square that is 30+1=31 square. I hope you understand my query.
waiting for your reply sir

[@rtpachhakchhuak2954]

This big square is already included in 30 total squares,dear learner yar

[@blazecube0075]

Very good and useful, I am an army commander in the midst of your fellow 193k subs :D

[@magdalenasseng3145]

My question is on the one we counted 72 squares. The first 30 is fine then the next 30 then the next 8. But my concern is for the last 4 squares. Is it not supposed to be 5 instead? Because of the middle part.

[@santhosh4265]

Yes I am also having same doubt .

[@santhosh4265]

Yes .l have a clarity on that.the centre square is counted in second 30. Observe it carefully
