With the first number being 1 (not zero), the 25th number is 11001 (base 2). This is 16 + 8 + 1 = 25 (in base ten). Each place value in the binary system is double the value to the right of it.
It is a number system that uses the digits 0 and 1 only. So 0 is written 0 and 1 is 1, but two in base 10 is written 10 in binary. The first digit is 20 or 1, the next is 21 or 2, the next digits is 22 This keeps going and any number can be written in binary or base two.
the Mayan and Chinese are the oldest.
Almost exactly like the decimal system, but the base is the number 2, instead of the number 10. This refers to the place-value system: in decimal, each digit has a place-value that is 10 times as much as the digit on the right; in binary, the factor is 2. It is helpful if you understand the place-value system in decimal first.
The term binary means based on two numbers only. It would be possible to use any two numbers for a binary system, however, since 0 and 1 are the first two numerals, it was considered reasonable to use those. It could just as easily have been 1 and 2. The advantage of a binary system is that it is easily converted to an electrical circuit state; one number means on, the other number means off. That makes it useful for computers, which are based on electrical circuits.
Binary
The first computer to use the binary number system was probably the Z1, started by Konrad Zuse in 1936. It was a mechanical computer, not fully programmable, but is still considered a computer.

It's the first even number It is the first prime number It is the only even prime number It is the base of the binary system If a number ends in 0,2,4,6 or 8 it is divisible by 2

In order to answer that, it would first be necessary to know the numbers that "O", "K", and "A" represent.

All numbers can be represented in a binary number system. Binary is the base 2 number system, meaning that there 2 possible values per place: 0 and 1. A decimal system allows for 10: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In a decimal system, you carry out and add a space once you pass 9. Thus, you end up with a 1 in the second place and a 0 in the first. The first space then counts up again. Similarly, a binary system adds a place when it reaches 2. In a decimal system, there are 10x numbers which can be represented by a system with x places. In binary, there are 2x possible numbers. If the number of places is infinite, an infinite number of values can be represented. Negative numbers can be represented in a variety of ways, from a dash as is commonly used in decimal to a 2's complement to a sign bit (i.e. a 1 or a 0 which will tell the reader or the machine the sign of the number).
It appears to have been first used by the Indian scholar Pingala, some time between the 5th and 2nd centuries BCE. See link for more.
