How to do multiplication ? Suppose you have to multiply 92 to 93, find their difference from 100, put them like this : 92 -8 93 -7 now subtract 7 from 92 = 85 (or 8 from 92, it is cross subtraction) the base is 100 so answer has to be in 4 digits now you multiply 8 and 7 = 56 so answer should be : 8556
9992 * 9932? Again put it as base 10000 9992 - 8 9932 -68 deduct 8 from 9932 = 9924 now multiply 8 to 68 = 544 the answer has to be in 8 digits : so answer is : 99240544
How to find squares of numbers ending in 5? Suppose you have to find squar of 95, just multiply 9 to hits higher digit and put 25 at the end. 9*10 = 90, dont forget 25 =9025 similarly, find square of 185, multiply 18 to 19 = 342 and put 25 : 34225
How to multiply 43 to 47 ? Here the unit digits are 3 and 7, when you add them, it is 10. so understand a simple trick for such cases : multiply 4 to next digit = 4*5 = 20 now multiply both the unit digits : = 21 the answer is 2021.
How to multiply 58 to 52? 8+2 = 10 so 5*6 = 30 8 * 2 = 16 so answer : 3016
How to multiply 123 and 321 in one go ? Assume 123 as ABC and 321 as EFG respectively. The simple (but long) formula is : AE / (AF+EB) / (AG+BF+CE)/(BG+CF)/(CG) =3 / 8 /14 / 8 / 3 (here 14 is two digit, so add 1 of this to 8 – the earlier digit) =39483
How will you square up 109 ? 109 = 100 + 9 so add one more 9 to it : 118 now take square of 9 and append it. = 11881
How will you square 1011? Add 11 again : 1011 + 11 = 1022 square 11 and append it : 1022121
How will you square 53? 50 + 3 = 53 so add 3 more to it : 56 now divide it by 2, we get 28 now append square of 3 to it. 2809 answer Note: here we have divided by 2, because 100/2 = 50 the base has to be 10 or any power of 10.
How will you multiply 303? 303 + 3 = 306 now multiply it by 3 = 918 now append square of 3 to it: 91809 Note : here we have multiplied by 3 because 100 * 3 = 300 (the base is 100)
How will you multiply 411? 411 + 11 = 422 now multiply it by 4 : 1688 now append square of 11 : 168921 answer. Note : we have multiplied by 4 because 100 * 4 = 400
How will you find square of 257? 257 + 7 = 264 now you divide by 4, 66 append square of 7 (base 1000) = 66049
How will you square up 126? We know that 1000/8 = 125, so take 125 as base 126 + 1 = 127 divide 127 by 8 : 15.875 now append square of 1 : = 15876 answer
How will you multiply 29 to 99? Instead of 29, werite 28 now deduct 29 from 100, we get : 71 so answer should be : 2871
