Prime and Composite Numbers | Maths

The video tutorial explains the concept of prime and composite numbers. Prime numbers are defined as whole numbers with only two factors: one and itself. Examples like 3 and 5 are given to illustrate this. The tutorial then introduces composite numbers, which have more than two factors, using examples like 4 and 24. The video also includes exercises to identify prime and composite numbers, emphasizing that a number can only be either prime or composite, not both.
