## Has anyone studied vedic Mathematics? The Hindu Vedas math code?

I recently was told about this by a strange man in a cafe. He could do amazing mathematical operations inhis head quickly and accurately. I tested him out and I had a calculator to check. he claimed it was all due his knowledge of the mathematical secrets of the Vedas. I found it odd, but he gave me plenty of evidence as to his skills, so I tend to believe him. Anyone else know of this?

Not strictly Vedic math, but there numerous short cuts in ancient Indian tratises on math. I formula like this is extracting the square root by addition and subtraction.

## Is 3 to the power of 100 a even or an odd number?

Hi. im trying o practice my maths so i bought some maths papers to practice but im stuck on one question on a NO-CALCULATOR ALLOWED MATHS PAPER.
The question was is 3 to the power of 100 even or odd?
but i don’t know how to work it out so please if you know the answer or how to work it out please tell me.
Thanks x

3^1 = 3
3^2 = 9
3^3 = 27
3^4 = 81
3^5 = 243

see that at 3^5 we start back at the last digit = 3

the 3 power series has only 3, 9, 7 ,1 in the unit position so all its powers are odd

## Math question? Help??? The odd numbers 1-49…?

The odd numbers from 1 to 49 are multiplied together as follows.
1 x 3 x 5 x 7……………x 45 x 47 x 49

What is the second last digit in the answer to this calculation?

(I have no idea how to do this. I tried it on a calculator, nothing (bunch of e31 things.) Is there a trick to it? Please tell me how you found it.
1)Tell me HOW you go it

2)I did try to use my calculater
I wrote it exactly as it was written in my book.

I think there is some trick to it, but I have no idea.

I’m not askign you to multiply them all together, just to help me figure out how i am supposed to find the second last digit.

Remember that 47 x 49 is the same as (40+7) x (40+9). Also, multiplying a 0 will result in a 0. So you could essentially remove the tens place of all the numbers and only multiply the 1 place.

In the example above 47×49=2303. The last number is 3.
Remove the tens place and multiply 7×9=63. The last number is 3.

Given this information you could multiply out only the 1’s positions.
So, for each tens position you have: (ones, teens, 20’s, 30’s, 40’s)
1x3x5x7x9 x 1x3x5x7x9 x 1x3x5x7x9 x 1x3x5x7x9 x 1x3x5x7x9 =
797,493,650,625.

58,435,841,445,947,272,
053,455,474,390,625

I had to break up the number due to length and the way Yahoo handles it.

Use the window’s calculator to have answers large enough to handle that problem.
