Converting Hexadecimal into decimal numbers

1. Hexadecimal numbers have some simularities to decimal numbers however, past the number 9 is represented using A,B,C,D,E,F.

2. For example using the number 35 (Base 16) we are going to convert this number into a decimal (base 10) number. First we multiply the number in the tenth collum by 16 therefore 16x3=48 and then we take the number from the units collum and then multiply it by 1 therefore 5x1=5 so we add together the numbers 48 and 5 which is 53. This is the method you use for converting hexadecimal (Base 16) numbers into decimal (base 10) numbers.

Converting Binary numbers into hexadecimal numbers

1.binary numbers are represented using 8 bit, 16 bit, 32 bit and 64 bit.

2. For example using the 8 bit binary number 10010110
