Zero was introduced initially, not as a number to be used in computation, but as a position marker to distinguish between such numbers as 123, 1203, 1230, and 1023. The Maya, about the 1st century ad, used a small oval containing an inner arc to denote zero. About five centuries later the Hindus began to use a circle or a dot as a symbol for zero; the dot later fell into disuse. These Indian mathematicians wrote numbers in columns, and they used the zero to represent a blank column. The Hindu word for zero was sunya, meaning empty, or void; this word, translated and transliterated by the Arabs as sifr, is the root of the English words cipher and zerZero was introduced initially, not as a number to be used in computation, but as a position marker to distinguish between such numbers as 123, 1203, 1230, and 1023.

Zero is itself a digit so the question does not really make sense. However, the non-zero digits are older than zero. For example, consider the Roman number system which had no zero.
Zero, since there is no underlined digit!Zero, since there is no underlined digit!Zero, since there is no underlined digit!Zero, since there is no underlined digit!
indian numerals do not have zeor '0' digit, arabs invented 'zero' 0.
4 Every digit between the leftmost non-zero digit and EITHER the right most non-zero digit OR the rightmost digit after a decimal.
100 is a 3 digit number.

Oh, dude, the leftmost nonzero digit is basically the first digit in a number that isn't zero. Like, it's the number that kicks off the party and gets things going. So, if you see a number like 503, the leftmost nonzero digit would be 5. Hope that clears things up for ya!

Zero is considered a significant digit when it is to the left or the right of the decimal point. It is also a significant digit when it follows a non-zero digit or when it is between two digits.
To round a number to a particular digit, look at the digit immediately to the right of your target. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.
If the first digit can be zero, there are 5,040. If the first digit can't be zero, there are only 4,536.
