For Maths Today we were working on some Prime And Composite Number math sheets. A Prime Number can be divided evenly only by one, or itself. And it must be a whole number greater than one. The Numbers inside the Prime Numbers are called factors. A whole number that can be divided evenly by numbers other than 1 or itself. For Example 9 can be divided evenly by 3 (as well as 1 and 9), so 9 is a composite number. This is my Explain everything about them.
