There is no such thing as subtraction. Just something to think about :)
There are numbers and there is an operation called addition. Every number has an additive inverse, an opposite value.
Example: The opposite of 4 is -4.
When we do addition between numbers like 5 and the inverse of 2: 5 + -2 this is usually what we're thinking of when we talk about subtraction. We could write it as 5 - 2.
But anyway, to answer your question,
Subtraction and division are derived from the principle operations of ADDITION and MULTIPLICATION.
