Did you noticed that he is writing inversely on the screen, to make us understand the correct way...

[@এসোশিখি-শ৯র]

I See I want to made this vedio. any one can help me

[@isee7283]

What ?

It's better to keep the numbers as rationals... decimals might affect the equation in analytic purposes

[@r_pyxl2663]

What are they writing on?

[@aliyawarsame7170]

thaks i understand

[@cupidsoldier1776]

What ? Lmao

[@deicidej89]

I’m impressed I mean you’re writing it backwards

[@madiadams7854]

he's just simply writing on a piece of glass and then during editing they flip the writing bc it would come out backwards
