How I Learned To Calculate Extremely Fast Youtube Hi, this video is the 1st part of the mental maths series where you will learn how to do lightning fast calculations in a snap even faster than a calculator . Build the answer in three steps. first, 2*7=14. 196, 7*4=2 8 =>add 2 to 196 and stick the 8 on the end, i.e 1988 . learn this trick to easily calculate the product of numbers just above a base (100,1000,10000). suppose you want to calculate (108*109) where the base is 100. add 108 and 9 to get 117. 1,204 5 17 32. just practice. pick two big numbers, multiply and divide and add and subtract them. – mathematician. jun 22, 2014 at 19:15. 1. the key to fast mental calculation is numerical fluency, not just practice and having memorized tables and algorithms. 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.

The quickest way is to start with the 4 from the 40 that we carried, then add on the 4 × 6 and 7 × 3: 4 4 × 6 = 28. 28 7 × 3 = 49. these addition multiplication pairs are quick to do with practice. again we can write down the “9” in the tens place of the final answer, and keep the 4 for the following step. 29136 × 5847. To calculate addition, employ the following steps: round up or down both numbers by adding or subtracting small values. perform the addition. adjust the result by subtracting or adding the rounded values to obtain the final sum. 5. how to know if a number is divisible by 9? to find a number is divisible by 9, calculate the sum of its digits.
