What is number in mathematics?
The difference between numbers and numerals is like the difference between ideas and symbols:
-
Numbers are abstract concepts that represent quantity or value. For example, the idea of "three" apples or "ten" fingers—those quantities are numbers.
-
Numerals are the symbols or written representations we use to express numbers. For example:
-
"3" is a numeral representing the number three.
-
"X" is a Roman numeral representing the number ten.
-
"10" is a numeral in base-10 representing ten.
-
So, numbers are the actual mathematical concepts, while numerals are how we write or speak about them.
