Number
A number may refer to any of the following:
1. Sometimes abbreviated as num, a number is any character that's 1, 2, 3, 4, 5, 6, 7, 8, 9, or 0. Any negative number is any earlier characters beginning with a hyphen; for example, "-12" is a negative number. Numbers have many relationships with computers. Examples include measuring the clock speed of a CPU (central processing unit) or the binary numbers that send the CPU instructions.
A number with a minus (hyphen) in front of it is known as a negative number and not a minus number.
