How to multiply ANY numbers the fast way - Fast Math Trick

[@Kikkodude]

For all of you wondering how to do it for 4+ digits here's how. For 4 digits, you do the same he did up until the 3rd digit. When you get to the 4th digit (counting from right to left) you multiply the 4th digit with the 1st digit, the 3rd with the 2nd, the 2nd with the 3rd, and the 4th with the 1st. After that you repeat the process you did with the first 3 digits with the last 3 digits. For 5 digits, you do the same up until the 4th digit as explained before. For the 5th digit you'd do the same as before. The 5th digit with the 1st, the 4th with the 2nd, the 3rd with the 3rd and so on. I know the explanation might be confusing, but this is the bets I can do. :)

Thank you so much! It is kind of similar to when you are learning how to quickly do the "multiplication by 11" trick and you then find the "multiplication by 111 trick". The same concept, but modified because of the number of digits.

Unfortunately, instead of this quick method, our kids are forced common core.... Which means 4 sheets of paper and 15 minutes will be used to get the same answer

At the beginning of the year he gave us all a comprehensive test on geography, covering things he hadn't taught us yet. I did fairly well. Third highest. Then at the end of the year he gave us the same test. I was at the bottom of the class. He finally ranted on me about how much of a worthless student I was. He said, At the beginning of the year I gave that test and you were at the top. At the end of the year you got about the same score. Everyone passed you up and you were at the bottom. What do you think that tells me? I said, It SHOULD tell you you're a lousy teacher. Clearly I picked that information up from other teachers along the way who were much better than you. But you taught me nearly nothing except how bad you are at teaching. He didn't have an answer for that. He just glared at me. Go ahead and stare, loser. I'm great at learning, but not from you. You sir, are the lowest common denominator. You are the cylinder that's not firing. Why are you even a teacher? You should be digging ditches or something.

[@x1thesoul172]

You basically did learn it in school. You’re still doing the same thing, but instead of breaking it down in rows and then adding, you’re summing those parts up as if they are broken down by place value. They probably don’t bother to teach this in school because they would have to spend the time explaining Why it works, and students would get so caught up in trying to recite the patterns they’d forget how to do multiplication altogether. Like, they’d either have to resort to the standard way.... which they know is tedious and may not have practiced as much, or this method, which works smoothly but if you haven’t done it in a while it could be easy to forget how to do it and why it works. ....given the choice, they’d try really hard to do the quick way, especially in a pinch. And if they forgot how to do it, this could leave them completely unable to do the problem.

[@robertjdunn3774]

I have used the same trick for some time but work from left to right. I put the carrys underneath and add them at the end. This can give an increasingly accurate estimate as you go along. You can then rule out answers that are going to be too high or too low.

[@sharonjuniorchess]

Another way which separates out the computation from the summation is to write the number sums separated by a comma (to denote the power of ten column one is working with i.e. units, tens, hundreds etc) so the carry is contained between the commas (called 'open numbers') until completion when the summation process compacts the number down to just single digits between each comma and pushes any carries into the next comma column at which point the commas can be removed and the number becomes a closed number (which is the normal hind-arabic number with each digit representing the powers of ten value). The advantage of this approach is that it can be done from left to right or right to left but it also provides a clear audit trail of how the student arrived at their answer and where they may be making mistakes. Is it in the multiplication process or the carry process? As one masters the process it can be done faster and even mentally. So 213 x 323 becomes 6, 4+3, 6+9+2, 6+3, 9 => 6,7,17,9,9 => 6,8,7,9,9 => 68799 [N.B. I have used '=>' to represent equivalence or becomes] For estimating you just stop at a significant point & enter the relevant number of commas or zeros to get your approximate number.

[@sr9fire]

@@sharonjuniorchess I love your approach using commas!

[@sharonjuniorchess]

@@sr9fire Thank you. The Vedic mathematicians use a slash but Norman Wildberger uses a comma and calls this form an open number; the comma separating the 10's powers columns. Its no different to how we handle money and I can have many different ways of 'making up' the same amount of money but there is only one way that we denote the actual sum i.e. in its closed number form. I find this method very useful when doing left to right multiplication but it works right to left as well. We need to bring back the playfulness of doing numbers which is what I find in the vedic approach.

[@JeffTheHokie]

Combine this with the major system (memorize numbers by converting them to consonants) and you can do this in your head. "Write down" the finished digits by turning them into words. 2=hen, 12=tuna, 212=nothing, 6212="shined on", etc. Carry digits on your fingers (thumb=5) You have a tens hand if you need it. To really show off (unless you're being graded), you can link the answer words to either rhyming pegs or memory palace locations. You can hand the paper back blank, and then call out all the answers.

[@ChosenMan37]

Can you show 4 digits time 4 digits and 5 digits. Is it the same method or different?

Yes and no. Calling it "Vedic" is a misnomer.

[@sharonjuniorchess]

Vedic maths was 'discovered' by Jagadguru Swami Bharati Krishna Tirtha, Shankaracharya of Govardhana Pitha (1884-1960). Whilst the method may well have been taught much earlier there is evidence that this method was used in a number of different cultures and may be the origin of the 'times' symbol we use to denote multiplication. The oldest known mathematicians are currently the Babylonians who counted in base 60 but used extensive tables to help them do their computations (like times tables). We still use the same system today (when we calculate the time in minutes & seconds). 100,000's of their tablets which were dug up in the 1920's have still yet to be translated. kzbin.info/www/bejne/n2qQi4N9pZZ0gKc

This isn't any faster than the normal method IMO, it's just different.

Its easier to understand imo and its only the "same speed" on paper, literally 😅 try doing both methods in your head

@@Peter_schluss_mit_Lustig - I did and it's just as fast for me. Sorry if your brain is too slow.
