Simple Definition:
Mathematics is the study of numbers [symbols used to represent quantities], shapes, and patterns [arrangements or sequences that repeat].
For example, in mathematics, we learn how to add numbers together. [Adding means combining two or more numbers to find their total.] We also learn about different shapes like triangles, circles, and squares. We can also study patterns like the Fibonacci sequence, where each number is the sum of the two previous numbers. [The Fibonacci sequence starts with 0 and 1, and each subsequent number is found by adding the two previous numbers, such as 0, 1, 1, 2, 3, 5, 8, and so on.]
Very Simple Definition:
Mathematics is about numbers [symbols that represnt the quantity or amount of something], shapes, and patterns [things that repeat themselves]. We use it to add numbers or find different shapes. For example, when we calculate the change we are owed, or when we draw a square on a paper, we are using math.
