title should really be "how to do multiplication without a calculator assuming you already know to how multiply in your head"

[danielmadrid]

They said we would use arithmetic in real life. They said there’s a reason they can’t just let us use calculators. Turns out the reason is getting high at 4am and freaking out about all the stuff you forgot from elementary school

[gianna]

this was not helpful. all you said was "just multiply and add zeros" you need to explain more as if you're teaching this for the first time

To the people in the comments that are upset because she didn’t explain the “basic” math or “break it down more” you are watching the wrong video she said assuming you already know basic math. so go watch a video on that then come back to this one. it would make more since after you learn your times tables.

I was like "Wow this lady is so talented to be able to draw backwards so we can read what she is drawing on the glass." But like... they prob just flipped the video, that would also explain why she is left handed (Because its less common of course)

[danielexplores]

so it turns out, I dont know how to do mental math .... any tips on how to memorize the basics? like 6x4? or how to work that out?

[gandalfsbeard]

Hi, how do you know to add both 0's when doing 640 x 40 = 2400? I can see the common sense side because 60 x 40 is obviously going to be a larger number than 640.. but what is the correct maths explanation for this?

[soumyamukherjee]

Really this !! I can almost calculate this in my head without any additional method!! XD

[wittydit]
