There are 3 ways to faster multiplication. Way I:Multiplying a 2-digit number by a 2-digit number.EX: 23X56=...First, you multiply the first numbers on the right( 3X6=18, carry the 1). Then you write down the 8.Then you cross multiply and add the answers, and the carried 1( 6X2=12, 3X5= 15. 15+12+1=28). Write down the 8, carry the 2. Then multiply the left numbers and add the carried 2( 2X5=10. 10+2=12). Write down the 12. The answer to 23X56 is 1,288. Way II: Multiplying a 2-digit number by a 3-digit number. EX: 234X56=... Multiply the right numbers first( 4X6=24). Write the 4, carry the 2. Then cross multiply with the four right numbers and add the answers, plus the carried numbe( 3X6=18, 4X5=20. 18+20+2=40). Write the 0 and carry the 4. Here's the extra part: Multiply the bottom-right number by the top-left number, and the middle two numbers. Add the answers, plus the 4 you carried( 2X6=12, 3X5=15. 12+15+4=31). Write down the 1 and carry the 3. Now multiply the top-left number by the bottom-left number and add the 3(2X5=10, 10+3=13). Write the 13. The answer to 234X56 is 13,104. Way III: Multiplying a 3-digit number by a 3-digit number. EX: 234X567=... First you do what you did in Way I( but with the four right numbers in 234X567), and carry the 2. Now you multiply the top-left number byt the bottom-right number(keep the product). Do the same with the top-right number and the bottom-left number(keep the product). Then the same with the middle numbers(keep the product). Now you add all the numbers you got( 2X7=14, 5X4=20, 3X6=18. 14+18+20+2=54). Write the 4, but carry the 5. Now you do the same thing you did in Way I with the 23 and 56, but make sure you add the 5 after you multiply 6X3. If you do this correctly, then you should get an answer of: 234X567=132,678 There are three more ways, but I will post it in a different article. I am a person who wants to show the world my discoveries. Like: n/0 = n(S)=A(1)/1(S)=A(1).<------ Alero formula. It says that: number times something equals anything times one divided by one times something equals anything times one. That was random, but OK because I am random. P.S. Your math teacher(regular or sub.) might not approve of the faster multiplication shortcut. I suggest you only do it at home. Bye now. Article by: FudgeSwordPerson
