A mathematical object that represents quantities, positions, sizes, measurements, etc.

- We often tend to confuse
*number*and*digit*, particularly in radio, television, and advertising communications, which is an error. In fact, digits are graphic characters that allow us to write numbers. In our number system, there are ten digits, which are 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. - Because the numbers 0 to 9 only use one digit, there can be some confusion. When that happens, the context allows us to find the solution.
