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.

kasam se yar... kya class tha!

[@annabenedict9168]

[@anupadas4691]

Thank you so much sir you teach me a new thing

[@BCHABARNAP]

THE best explanation I have come across among other channels

[@babumohan5776]

Brilliant knowledge you have sir thank you so much

[@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.

Thank u Sir . Im so weak in reasoning plis update more videos

[@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

Dear Sir, In Tricks 415 shortcut 13 the total number of squares comes to 54 and not 50. Please check and correct. Thanks. Please respond.

[@alexarainderifas3665]

Thank you So much Teacher is it ok when I call you teacher

[@AjoyDey25]

Thank you sir🥰🙏

[@jeeniknikita]

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
