How To Multiply Two Different Numbers In Fastest And Quickest Ways Step 1: multiply the given number by 10. (6×10 = 60) step 2: multiply the given number by 2. (6 × 2 = 12) step 3: add the result obtained from step 1 and step 2 (60 12 = 72) hence, 6 ×12 = 72. get more such tips and tricks to solve mathematical problems quickly and get interactive videos, by downloading byju’s app. #fastmathtricks#mentalmath#mathtrick using this math trick for fast calculation you will be able to multiply any pair of three digit numbers with each other.
How To Multiply Two Different Numbers In Fastest And Quickest Ways In long multiplication, we have to multiply every digit of the first number by every digit of the second number. if the two numbers each have n digits, that’s n2 (or n x n) multiplications. In this math trick video we look at an easy way to multiply numbers where the ten’s digit is the same and the one’s digit adds up to 10. example: to find 52 × 58. take the ten’s digit and multiply it by the next highest number. 5 × 6 = 30. next, multiply the one’s digit. 2 × 8 = 16. the answer is 3016. Step 1: multiply the 2 times the 4. 2 x 4 = 8. step 2: put all four of the zeros after the 8. 80,000. 200 x 400= 80,000. practicing these fast math tricks can help both students and teachers improve their math skills and become secure in their knowledge of mathematics—and unafraid to work with numbers in the future. Just learn one times two digit inside and out, then do this. 69 * 89. go 6*89 = 534. add this to the first two digits of 9*89 = 801. do it: 534 80 = 614. glue the 1 on to the end. we get 6141. this has to be the best way since i'm a low life chemist but can do them in seconds (no pencil or pen).

Mengxin li for quanta magazine. four thousand years ago, the babylonians invented multiplication. last month, mathematicians perfected it. on march 18, two researchers described the fastest method ever discovered for multiplying two very large numbers. the paper marks the culmination of a long running search to find the most efficient procedure. 12×12 = 144. and this gives us one more trick. when the numbers we are multiplying are separated by 2 (example 7 and 5), then multiply the number in the middle by itself and subtract one. see this: 5×5 = 25 is just one bigger than 6×4 = 24. 6×6 = 36 is just one bigger than 7×5 = 35. 7×7 = 49 is just one bigger than 8×6 = 48.
