Math Is Fun Forum

I will not get stuck since i have the solutions book(yes a solutions book is also available there.....). Yeah i will send you the questions which i find difficult and interesting.

Hmmm, I see it cant be helped; in india the book is available at a price of Rs.250 which is 3.75 dollars!!!!!!!!!!!!!! But the book has to travel a whole journey to your usa crossing thousands of miles of land and sea in between me and you so its price is 21.95$(which in inr is 1464.87 rs).

You will not find free download; sorry you to buy the whole book.

Here's the link for the book available online in amazon(.com):

Florida is the southeasternmost U.S. state, with the Atlantic on one side and the Gulf of Mexico on the other. It has hundreds of miles of beaches. The city of Miami is known for its Latin-American cultural influences and notable arts scene, as well as its nightlife, especially in upscale South Beach. Orlando is famed for theme parks, including Walt Disney World.

Again Experimental Math means???

And BTW did you check it out? How did you find it?

It is clear; Agnishom is from Tamil Nadu which is in India and he also told that you are his maths teacher in school so it is clear you are(though you have written that you were born in Brooklyn in New York). Aap Mujhe ullu ithni aasaani se nahi banaa sakte aur agar aap indian hain toh aapko hindi tho zarroor aata hi hoga aur aap samajh bhi sakte hain ki main kya likha hun.

Thanks Bob I'll try to learn as soon as possible.

Hi Superlynx,
3/7+3/5=_/35+_/35
3/7+3/5=[(3*5)+(3*7)]/35=(15+21)/35=36/35
Now,_/35+_/35=(_+_)/35
Now since the value of the two nos. will be 36 so we can have 36/2= 18 possible answers. They are:
0 & 36
1 & 35
2 & 34
3 & 33
4 & 32
5 & 31
6 & 30
7 & 29
8 & 28
9 & 27
10 & 26
11 & 25
12 & 24
13 & 23
14 & 22
15 & 21
16 & 20
17 & 19
18 & 18
I think you're a little confused with the addition of fractions; hope this helps.
(Note: I've not learnt to use Latex format yet so I've written in normal format using the possible symbols in keyboard to denote fractions hope you understand and are not confused.)

Hey, I,ve found a book named BMA'S Talent Hunt Maths which has very difficult problems. Even our fiitjee's maths problems are not as difficult as that. I dont know whether it is available outside the indian subcontinent or not but it is an outstanding book for maths. A must buy book for iit aspirants

After getting more details i found that the total no. Of possibilities are 10C2 or C(10,2)  =10!/(2!*8!)=45
