note
There are 10 digits, 0 to 9, but every number can be written with them. Maths: names a place in a number, not an amount: in 58 the digit 5 stands for 50. Trap: «the digit 5» and «the number 5» are not the same thing; «two-digit» tells the size of a number (10 to 99), not that there are two of something.
