Euclid’s Elements. One of Leonardo’s contributions to mathematics was his introducing the Decimal Number system into Europe. He was one of the first people to introduce the Hindu-Arabic number system into Europe. Fibonacci also introduced the Decimal Positional System‚ which originated from India and Arabia.

You use the method of subtraction‚ if you can subtract the number that corresponds with the value you “2” you are dealing with you need to place a 1 under the 2 that corresponds with the number you are subtracting. This is like saying yes the number works. If it doesn’t subtract you place a zero underneath the “2” that you are dealing with‚ this is like saying “no” it doesn’t represent anything. That is the basic formula for doing binary

base 16 and (52) base 8 both refer to the same quantity though the representations are different. When we type some letters or words‚ the computer translates them in numbers as computers can understand only numbers. A computer can understand positional number system where there are only a few symbols called digits and these symbols represent different values depending on the position they occupy in the number. A value of each digit in a number can be determined using The digit The position

24 hours‚ each hour into 60 minutes and each minute into 60 seconds (O’Connor and Robertson‚ 2000). Like our own decimal system today which is a positional system comprised of nine special symbols and a 0 to denote an empty space‚ the Babylonians only had two symbols to produce their base 60 system. However‚ although the Babylonians had a fairly positional system‚ it also had some element of a base 10 within it. This is because the number 39‚ for example‚ was built from a unit symbol and a ten symbol

4.3 4.3 Conversion Between Number Bases 169 Conversion Between Number Bases Although the numeration systems discussed in the opening section were all base ten‚ other bases have occurred historically. For example‚ the ancient Babylonians used 60 as their base. The Mayan Indians of Central America and Mexico used 20. In this section we consider bases other than ten‚ but we use the familiar HinduArabic symbols. We will consistently indicate bases other than ten with a spelled-out subscript
