It is a symbol used to count, measure, or label. The written symbols themselves vary widely, from heiroglyphics, scratches, marks, pictures, alphabetical figures, to what we think of as numerals. In the late 1700's, the French Academy gave us the final number (zero), and a symbol (0) for it. Until then a hyphen - was used (for instance, ten was before written as 1-
Decimals then appeared in the number system, and pretty much lead to what we have now. It will change. It already is changing in binary, and hexadecimal systems.

A number is a mathematical concept that represents a quantity or a value. Numbers can be used for counting, measuring, and performing mathematical operations like addition, subtraction, multiplication, and division. There are different types of numbers, including natural numbers (1, 2, 3...), whole numbers (0, 1, 2, 3...), integers (-3, -2, -1, 0, 1, 2, 3...), rational numbers (fractions or decimals that can be expressed as a ratio of two integers), and irrational numbers (numbers that cannot be expressed as a fraction and have infinite non-repeating decimals, such as √2 or π).
To understand the concept of numbers more deeply, you can study mathematics, which is the field that deals with the properties, relationships, and operations of numbers. Mathematics covers a wide range of topics, including arithmetic, algebra, geometry, calculus, and more. Exploring these different areas of mathematics will help you understand the nature and significance of numbers in various contexts.
