An interesting demonstration of multiplication by use of an alternate method. Technique essentially creates logarithms to work. I am sorry but I would like to credit the author, but I do not know who it is.

If you want to become good at math go to my youtube channel: (Mathmatchpoint). In my channel I will teach you everything about math step by step. I will start with teaching you (The Important basic math skills) and then I will teach you the more advanced math topics. Just click on Playlists when you are on my channel and you will be able to watch my math videos in order. I promise that I will teach everything in an easy way. Math is easy if you have a good teacher.

@jacksawild It is very transparent and valid. It is too slow for the size and accuracy for those calculations. Essentially a computer does this but very quickly.

thx dude it totally helped me

this trick slower and takes more space than the traditional method..

they should teach this in school

nice

cool

what about 275×685 would it work? can you make an example for a larger number like the number i just put down thanks in advance and MerryChristmas.

Im gonna do this on my Maths test to make the examiner think WTF? how did he get the answer with that LOOL

im trying this in math class and show my teacher haha

brilliant

I dpnt get thos quite? It works with low numbers but if its like 163×128 then how do you dp? Please help!

@AJFlLMS It can b e done using the same technique but it is very tedious

@klaraine1515 zero is a blank when involved in any technique the character “0″ is just a place holder

@jacksawild It is very transparent and valid. It is too slow for the size and accuracy for those calculations. Essentially a computer does this but very quickly.

@binasheikh1974 Zeros are blanks – “0″ is just a place holder.

@mohamedhakkmed follow the instructions on sums greater than ten

@My6T1 don’t recommend it although it should work if you can keep track of decimal location

@iTyGuy32 just follow the technique – it is explained

@shimesaoshi yes it can – it leaves a blank

@jackie6197 need to still keep a place for the blank or zero

@Tenshionnanoko128 possible but unrealistic

@Retroshooter123 read the notes I did not do this I solely posted it

@Retroshooter123 you add the diagonal

…What? That’s so weird!! I really am excited to try this out…lol

@Retroshooter123 They didn’t, that was just a visual to show you add those intersections.
