The Roman numerals were loosely based off of the Egyptian numerical system, using single figures to show numbers in powers of 10. However the Egyptian was also slightly more advanced they had two ways in which to represent their data. Both in written numbers and through words, not only that but they could show fractions, negatives and decimals.
The ancient Egyptians used the symbol of a trachea connected to a heart to show the number zero, it also doubled up as a way of showing negatives as any number after this was a negative. The showed fractions as a mouth symbol, but could only show simple fractions such as 1/345 or 1/67, the numerator was always 1 except for in two fractions, 2/3 and 3/4 which along with 1/2 had their own separate symbols. They also had their own symbols for addition and subtraction, two feet. If the feet pointed right: addition, left: subtraction
