The following are the Prime Numbers between 1 and 100: -

2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67

71 73 79 83 89 97 (Note: They are all odd numbers except for 2)

__Base Numbers__**
**

A Base Number is a number from which all calculations are made. Usually
this is 10 as we practise our Maths in
the **Denary System** with a base 10
number. i.e. Once we reach 10 in counting, we
go back to 1 and continue adding digits until we reach the second 10, i.e. 20.

__Cardinal Numbers__**
**

A Cardinal Number is any number which is used in counting such as 40, 41, 42 or 5, 10, 15, 20 etc. Numbers, which follow each other without any gaps, are called consecutive numbers.

__Whole Numbers__**

A Whole Number is any number, which does not have any fractions or parts
(or remainders) with it. E.g. 2, 5, 67, etc. Its mathematical name is **integer**. Whole numbers can be either
positive or negative numbers.

Note: The digit 0 can also be a whole number.

__Mixed Numbers__**

A Mixed Number is one that contains both whole numbers and fractions. E.g. 11 (This can also be called a “Mixed Fraction”).
