Decimal - 0-9
Binary code, it's made up of 0's and 1's
Probably the most common example is the basis of a number system, such as the commonly humanly used base 10 or the binary base 2 used in computers.
It is possible to have numbers in ANY base. Binary, octal and hexadecimal are used extensively in computers. Furthermore, the base can be any positive number - it does not even need to be rational.
Computers are based on a binary number system.
base eight is important because it is used for digital displays in computers.
10 Base 2
It turns out that using the binary system - base 2 - requires circuits that are extremely simple, compared to circuits that manage decimal (base 10) numbers. So, internally, computers do lots of stuff in binary. Octal and hexadecimal numbers are used as shorthand for binaries, to make them readable for humans. This is because on average, a number written in binary digits requires 3-4 times as many digits as a number in decimal. Each octal (base 8) number simply represents three bits (binary digits); while each hexadecimal (base 16) number represents 4 bits.
The format by which computers express number is hexadecimal format. In this format the base of numbers is 16 as opposed to 10.
The octa or octal numeral system, which is also known as oct, is a base-8 number system used in computers. This number system uses only digits 0 to 7.
The exponent tells the number of times the base is to be used as a factor.
The number system commonly used by humans is base-ten.
The number that indicates how many times the base is used as a factor is the exponent, or power.
An exponent shows the number of times a base is used as a factor.
