3. double digit round. one of my personal favorites is the double digit round. this technique is useful for multiplying two double digit numbers. first, think of a nice, round number to which both of our numbers are closest. take 92 x 98, for example. both are close to 100, so we subtract them from 100 to get 8 and 2. Here, the sum of the unit digit is 10 (2 8 = 10) step 1: multiply unit digits: 2 × 8 = 16. step 2: multiply the digit 2 with its consecutive number 2 × (2 1) = 2 x 3 = 6. step 3: append 16 to the right side of 6. hence, it becomes 616. therefore, 22 × 28 is 616. case 3: multiplication of the given number by 9 n. (9, 81, 729).

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. 1. multiply by 10, then remove that number once for 9. when multiplying by 9, you need to multiply by 10 and then remove that number once. it’s one of the easier multiplication tricks for 9 and can be done quite quickly. e.g., 9 x 67 is 670 – 67, which is 603. 2. the double double multiply by 4 trick.

Many people feared of math. but it's really required to develop our brain. challenge your brain on a regular basis.it's an easy math tricks. practice and you. 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.
