Odd numbers are defined as numbers of the form 2n+1 for some integer n. Since 0 is an integer, 2x0+1=1 is an odd number. Another way to think of it is that an odd number is one that is not even. An even number is one of the form 2n for some integer n. 1 is not even so it is odd. This means 0 is even, by the way.

Can you get a odd number and subtraction 1 and get a odd number?
no physically you cannot because before an odd number is a even number.
Why if you multiply odd number with another number the result is always odd number?
Well, the question is why. The first number is "even" + 1. Multiply both of these by your odd number. Now the "even" times "odd" is even, because every "1" in the odd number becomes a "2". And then the remaining 1 times "odd" must be odd, which is an even +1. Add it all up and you get evens everywhere except that final "1". So the result is even + 1 which is odd. There is a quicker way if you know how to multiply bracketed terms: odd x odd = (even + 1)x(even +1)= even x even +even +even +1 = must be odd. ========================== You've just read a truly impressive answer to a question slightly different from the one that was asked. The part of the question that comes after "Why if ..." is a false statement. If you multiply odd number with another number, the result is odd number ONLY if the nother number is also odd number.

1 is the 1st odd number 3 is the 2nd odd number 5 is the 3rd odd number and so on 7 is the 4th odd number and so on if x is the 1000th odd number then x=2*1000-1=1999
What is the 102nd odd number?
The nth odd number is 2n - 1 So 102nd odd number is 2*102 - 1 = 204 - 1 = 203
If 1 is the first odd number what is the 400th odd number?

Why when you multiply an odd number with another odd number the result is a odd number?
yes, the product of 2 odd numbers is always an odd number. Well, the question is why. The first number is "even" + 1. Multiply both of these by your odd number. Now the "even" times "odd" is even, because every "1" in the odd number becomes a "2". And then the remaining 1 times "odd" must be odd, which is an even +1. Add it all up and you get evens everywhere except that final "1". So the result is even + 1 which is odd. There is a quicker way if you know how to multiply bracketed terms: odd x odd = (even + 1)x(even +1)= even x even +even +even +1 = must be odd.
