Numbers for people

There are different ways of giving symbols to numbers. These methods are called

**number**systems. The most common**number**system that people use is the base ten**number**system. The base ten**number**system is also called the decimal**number**system. The base ten**number**system is common because people have ten fingers and ten toes. There are 10 different symbols {0, 1, 2, 3, 4, 5, 6, 7, 8, and 9} used in the base ten**number**system. These ten symbols are called digits. A symbol for a**number**is made up...Numbers for machines

Another

**number**system is more common for machines. The machine**number**system is called the binarynumber system. The binary**number**system is also called the base two**number**system. There are two different symbols (0 and 1) used in the base two**number**system. These two symbols are called bits. A symbol for a binary**number**is made up of these two bit symbols. The position of the bit symbols shows how big the**number**is. For example, the**number**10 in the binary**number**system really means 1 times 2...English has special names for some of the numbers in the decimal number system that are "powersof ten". All of these power of ten numbers in the decimal number system use just the symbol "1" and the symbol "0". For example, ten tens is the same as ten times ten, or one hundred. In symbols, this is "10 × 10 = 100". Also, ten hundreds is the same as ...

Natural numbers

Natural numbers are the numbers which we normally use for counting: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, etc. Some people say that 0 is a natural

**number**, too. The set of all natural numbers is written as N {\\displaystyle \\mathbb {N} } . Another name for these numbers is positive numbers. These numbers are sometimes written as +1 to show that they are different from the negative numbers. But not all positive numbers are natural (for example, 1 2 {\\displaystyle {\\tfrac {1}{2}}} is positive, but not n...Negative numbers

Negative numbersare numbers less than zero. One way to think of negative numbers is to use a

**number**line. We call one point on this line zero. Then we will label (write the name of) every position on the line by how far to the right of the zero point is. For example, the point one is one centimeter to the right, and the point two is two centimeters to the right. However, the point one centimeter to the left of the zero point cannot be point one, since there is already a point called one. We t...Integers
