Hi;

Yes, I try. Numbers coincide. I notice right now that MathIsFun square is square array of Delannoy numbers (A008288 of OEIS).

Hi everyone;

I have carefully studied all Pascal's squares and in some of them I found some interesting successions. In this square, that MathIsFun proposed:

1 1  1  1
1 3  5  7
1 5 13 25
1 7 25 63

The sum of the numbers of every diagonal give Pell numbers (A000129 of OEIS).

1=1
1+1=2
1+3+1=5
1+5+5+1=12
1+7+13+7+1=29

Regarding my Pascal's square:

1     1     2     4     8
1     1     2     4     8
2     2     4     8    16
4     4     8    16   32
8     8    16   32   64
16   16   32   64  128

The sum of the numbers of every diagonal give numbers of 1's in all compositons of n+1 (A045623 of OEIS).

Hi;

Add the numbers above, left and diagonal-above-left, just like the square of MathIsFun. But in mine also the numbers in the first row and in the first column are exponents of 2, obtained by the sum of the numbers.

#56 Re: This is Cool » Pascal's square » 2012-10-30 22:27:38

I also find another square, similiar to that of MathIsFun. The only different is that numbers on the first column and on the first row are exponents of 2. This is the square:

1  1  2   4
1  3  6  12
2  6 15 33
4 12 33 81

#57 Re: This is Cool » Pascal's square » 2012-10-30 19:24:12

A Pascal's square has more rules And possibilities than a Pascal's triangle.

#58 Re: This is Cool » Pascal's square » 2012-10-30 10:27:23

Well, this

1  1  1  1
1  3  5  7
1 5 13 25

Is a Pascal's square, similar to the triangle. The rule is the same, but numbers are very different.

#59 Re: This is Cool » Pascal's square » 2012-10-30 09:53:50

Of course. There are so many rules that we can use. For example we can only add the numbers in each row, or in each column, using different kinds of successions. These mustn't be just Pascal's square with one rule.

#60 Re: This is Cool » Pascal's square » 2012-10-30 07:42:29

Hi;
Here is the proceedings:


  1

   1 = 1
   =    =
   1 = 1

   1 + 1 = 2
   +    +    +
   1 + 1 = 2
   =    =    =
   2 + 2 = 4

#61 Re: This is Cool » Pascal's square » 2012-10-30 05:54:32

I think that the square with prime numbers is not a Pascal's square, but it's still an intersting disposition of numbers.

#62 Re: This is Cool » Pascal's square » 2012-10-30 05:24:03

The sum of the numbers of each row doesn't give a right result, but all numbers are the product of the prime and all exponents of 2.

#63 Re: This is Cool » Pascal's square » 2012-10-30 04:53:06

I tried. This is the result:

2    3    5    7    11
2    3    5    7    11
4    6   10   14   22
8   12  20   28   44
16 24  40   56   88

#65 Re: This is Cool » Pascal's square » 2012-10-30 02:23:44

Hi everyone;

I notice that in Pascal's square I can begin with every number instead 1 And the numbers of the square are exponents of 2 multiplied by that numbers. Here an example with 3:


3       3       6      12      24      48       96

3        3       6      12      24      48       96

6        6      12     24      48      96      192

12     12     24     48      96     192     384

24     24     48     96     192    384     768

48     48     96    192    384    768    1536

96     96    192   384    768   1536   3072


Which is the result of

3x1  3x1  3x2  3x4

3x1  3x1  3x2  3x4

3x2  3x2  3x4  3x8

3x4  3x4  3x4  3x16

#66 Re: This is Cool » Infinity multiplied by infinity » 2012-10-29 21:29:31

And also infinity divided by infinity = undefined.

#67 Re: This is Cool » Infinity multiplied by infinity » 2012-10-29 19:34:53

I agree with anonimnystefy, infinity-infinity is undefined.

#68 Re: This is Cool » Infinity multiplied by infinity » 2012-10-26 20:17:35

I agree with you. I see infinity like a way to define our universe. As I said before if we find the biggest number in the world we can add one and we will have a new number, bigger than the previous number. So we can go on we will never find a final result, but we can't prove that infinity exists because we will never reach infinity, in each field of science. We can only theorize his existence, But I think that infinity is a fundamental concept for understand mathematics.

#69 Re: This is Cool » Infinity multiplied by infinity » 2012-10-24 20:59:27

If we will find the largest number we can  currently store in a computer, we can plus 1 and we will have Another largest number.

#70 Re: This is Cool » Infinity multiplied by infinity » 2012-10-24 20:38:01

But if infinity will be eliminate, numbers will be infinite or not?

#71 Re: This is Cool » Infinity multiplied by infinity » 2012-10-24 20:10:30

Well, no one can decide what is better Regarding infinity, we can only have a theory.

#72 Re: This is Cool » Infinity multiplied by infinity » 2012-10-24 18:59:55

I think that eliminate infinity is absurd. Infinity is a way to define where numbers and universe can arrive.

#73 Re: This is Cool » Infinity multiplied by infinity » 2012-10-24 18:23:03

Hi;

This small movement wants to eliminate infinity or operations with infinity?

#74 Re: This is Cool » Infinity multiplied by infinity » 2012-10-24 17:54:50

Ok. This is most Plausible hypothesis.
