Easy way to write square of numbers up to million WithOUt intense calculation !!!!
2
Mathematics can be fun if we make learnings creative Today I am going to introduce a good method to write squres of number up to millions without intensive calculation . We all can remember squares of numbers up to 15 or max 30 . After that it is hard to remember or slight intensive calculation need . If I ask u to write squares of numbers up to 100 in 30 miniuts without multification . Can u write??? Probably no .11 But after this session u can write it with very less efforts . LETS START!!! -4

It's a simple addition method . Keep adding odd nu method : lets begin It's a simple now after this keep on adding odd nu . What is first odd nu??? . I is neither odd or even nu . 3 not I Now add first odd nu in answer of (now add first odd nu 3) (l +3 -4) (now add next odd nu is 's ans) (4+5 = 9) Same way keep on adding odd nu in previous answer (9+7=16) (1 6+9 = 25) (25+11 = 36) (36+13 = 49) (64+17 = 81) (81+19 = 100)

= 121 =144 =169 = 196 =225 =256 =289 =324 v/ =361 v/ -400 (100 +21 = 121) (121+23 = 144) (144+25=169) (169+27 = 196) (196+29=225) (225+31=256) (256+33=289) (289+35=324) (324+37=361) (361+39 = 400) v/ Same way keep on adding continuous odd nu and u can get squares up to million i time without intense multification . ess

Apart from this , if smone ask u to write from middle — example right square's of 30 to 40 . Then how will u write??? If smone ask from 35-40?? If smone ask square of 98 or any middle number?? This was just a demo — I have lots of techniques through which u can answer all above questions within no time without intense calculation . Will keep updating . Enjoy the learning . Maths is real fun if u use some cool techniques in all sections like algebra geometry and much more ... Thank you !!
