what do the two zero in decimal mathematic
Roman numerals are very difficult to do mathematics with, and do not work at all in advanced mathematics as the roman numeral system has no concept of zero, negative numbers, fractions, powers, or decimals.
The Arabs. Roman mathematics suffered from lack of a zero. They could not do multiplication or division.
Rational value refers to a quantity that can be expressed as a ratio of two integers, where the denominator is not zero. In mathematics, rational values can be represented as fractions, decimals that terminate, or repeating decimals. This contrasts with irrational values, which cannot be expressed as simple fractions, such as the square root of 2 or π. Rational values are fundamental in various areas of mathematics, including algebra and number theory.
Real numbers
Two decimals are equivalent only if everything from the decimal point to the last non-zero digit is the same in both of them. Additional zeros after that don't matter.

In mathematics zero has no size.
Any negative decimal comes before zero in decimals.
Two decimals that are equivalent to 9.50 are 9.5 and 9.50. The decimal 9.5 is equivalent to 9.50 because the trailing zero in 9.50 does not change the value of the number. In both cases, the number represents nine units and five tenths.
There is no answer. Division by zero is forbidden in mathematics.
