Class in mathematics refers to a group of objects or numbers that have similar characteristics or properties. It's like a group of friends who all have something in common, such as liking the same type of ice cream.
Let's say we have a class of numbers called "even numbers." These are numbers that are divisible by 2 and have no remainder, like 2, 4, 6, and so on. Another class could be "odd numbers," which are numbers that can't be divided perfectly by 2 and have a remainder of 1, like 1, 3, 5, and so on.
By putting numbers into classes, we can group them together and better understand their properties. It's like organizing toys by type or color. This helps us make sense of things and solve problems more easily.
