Brilliant, isn't it?
And finally, take a look at this symmetry:
1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111=12345678987654321
Allah alone is sufficient for me.
I am a Muslim I say, "laa ilaaha illallaah Muhammadur-Rasoolullaah." There is none worthy of worship except Allaah, Muhummad is the Messenger of Allaah.
People, Mohammad (saaw) most certainly loved maths as there are mathematical "miracles" in the holy Qur'an. and if you look it the other way, Allah himself/herself loves math.
Islamic civilization gave us some of the best mathematicians of all time.
how about this - except for the 1st one (1x1=1) they all end with 41, and start with 15 (except the 2nd one)
1 x 1 = 1
121 x 121 = 14641
12321 x 12321 = 151807041
1234321 x 1234321 = 1523548331041
123454321 x 123454321 = 15240969373571041
12345654321 x 12345654321 = 152415180613625971041
Well there are some topics in Maths that make me bore
but overall i like Maths and specially algebra
but Maths need practice then only u will be able to get best in
Maths
i think if they taught us stuff like this in school more people would have loved maths,
but who cares about perimeters and the angle inside a triangle and bla bla, the schools make maths boring
but generally maths is kinda ok
You see akhi, before you get to 'cool' stage of maths, you have to get past the 'uncool' stage. I mean difficult maths solved makes you feel clever which makes you feel cool. But t get there, easy maths steps ought to be crossed first.
