Binary and decimal numbers are numbers with a different base than the standard 10. Binary is a base-2 number system, and decimal is a base 10 number system. For binary numbers, there are only two digits: 0 and 1. For decimal numbers, we use ten digits: 0 through 9.
Binary numbers are used in computing and computer science. Decimal numbers are more commonly used by mathematicians and scientists in their work, while binary is still widely used as a basis for computer programming.
Binary numbers are used in computers. They only have two digits, which makes them easier to use and calculate with. Decimal numbers are used in everyday life. They have ten digits, which make calculations more difficult and time consuming.
