How To Mentally Square Any Number Ending In 5 By Hemanth Math How to square any numbers in your head fast mental math trick here: watch?v=geuydhmg0jy there is barely any calculation needed to. The indian vedic ‘sutra’ gives the following algorithm to compute the square of any number ending in 5: 1. decompose the number (ending in 5) into the last digit (5) and the digits preceding. Append '25': 56 followed by '25' gives you 5625, which is the square of 75. why does this work? this trick works because of the way numbers ending in 5 are structured. when you square a number ending in 5, you're essentially multiplying (10x 5) by itself. this expands to: (10x 5) 2 = 100x 2 100x 25. notice the 100x 2 100x part? this. Take this product and attach a 25 to the end. the 25 comes from the 5 from the end of the original number. in our case, we would add a 25 to the 20, and come up with a final product of 2025. complete math: 45 original number 4 take off the 5 (4*5=)20 multiply the number (x) by one more than itself (x 1).

This will work for any number, great or small and is one of the fastest tricks you'll learn. to find the square of a two digit number ending with 5, take the first digit, multiply by itself plus one, and then put "25" after it. example: to find 55², compute 5 × 6 = 30. the answer is 3025. this will also work with larger numbers. For example, 97^2 61^2=101 (9^2 7^2)=13130. 972 612 = 101(92 72) = 13130. mental math tricks are a collection of techniques, some based on algebraic manipulation and some on visualization, that aid in large arithmetic computations.
