Math Is Fun Forum

Saw it. Hmm nice. I think the link should be mentioned in the mif website.

They could have launched a different website maybe...mmm... named physicsisfun.com. There would a similar forum for physics too. We would call it PIF. Or, more broadly a website dedicated to science called SIF.

Yes, it says that only.

You can find it out here:https://en.wikipedia.org/wiki/Maryam_Mi … earch_work

You can also try one more formula for

Hmm, excellent!

Actually there are 13. They all are listed below in brief.

1. A number of the nth row and nth position getting found out by Combiantion.

2.Existence of Fibonacci Sequence as bob showed above.

3.Shading Odd nos. in a Pascal's Triangle gives Sierpenski triangle series.

4.HCF of any row of a prime no. excluding 1 is that prime no. itself.

5.If you draw a hockey stick starting from an extreme end (that is a 1)and make a Hockey Stick,with only 1 number in the "J", the sum of all nos. in the stick = to the no. in the "J" of the hockey.

6.Adding nos. of the nth row give value as (2^n)

7.The nos. of the 2nd diagonal are the counting nos., the nos. in the 3rd diagonal are triangular nos., in the fourth are tetrahedral nos. and so on

8.The nos. of the nth row are the digits of 11^n.(From 11^5, it begans to overlap itself)

9.The pascal's triangle is symmetrical

10.Existence of catalan nos.

11.Pick any number inside Pascal’s triangle and look at the six numbers around it (that form alternating petals in the flowers drawn above). If you multiply the numbers in every second petal, you’ll end up with the same answer no matter which of the petals you start from.

12.Pick any counting number from along the first diagonal and square it. Then look at its two neighbours that lie deeper inside the triangle – they’ll always add up to that very same square number.

13.If you add up every single number in the first n rows, you’ll get the nth Mersenne number.

What are you learning?

What mistake did you make?

Hi all,

I saw this post today and saw the probs on log. Well, they are not bad, they are good. But you can also try these problems here by me (Credit: to a book):
