Long MultiplicationA short page on Long Multiplication "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20070807 13:06:25
Re: Long Multiplicationlooks good to me! What are you using to make those litle videos? A logarithm is just a misspelled algorithm. #3 20070807 13:29:19

Re: Long MultiplicationI made a video on long multiplication, a method I made up from something suggested in 5th grade to me. igloo myrtilles fourmis #5 20101221 16:55:30
Re: Long MultiplicationHi John E. Franklin; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #6 20101221 17:57:24
Re: Long MultiplicationWhat an interesting method! It seems quicker than the normal method, though not as transparent. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #7 20101228 08:10:42
Re: Long MultiplicationThanks for the comments guys!! Happy ice skating at the arena!! igloo myrtilles fourmis #8 20101228 16:40:04
Re: Long MultiplicationIs there any pizza left? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20101228 17:11:03
Re: Long MultiplicationSorry, no pizza left immediately available unless we go out to the pizza parlor, which would taste even better. I'd like to see a pizzamath video in the restaurant next!! igloo myrtilles fourmis #10 20110124 15:29:20
Re: Long MultiplicationLong multiplication is the method of multiplication that is commonly taught to elementary school students throughout the world. It can be used on two numbers of arbitrarily large size or number of decimal digits. The numbers to be multiplied are placed vertically over one another with their least significant digits aligned. The top number is named the multiplicand and the lower number is the multiplier. The result of the multiplication is the product. Last edited by Cecil Ned (20110124 15:33:32) #11 20110124 15:31:40
