Addition is a fundamental mathematical operation that has been used for centuries. It is not attributed to any specific individual, as the concept of combining quantities to find a total has been developed independently by various ancient civilizations across the world.
The inverse operation of addition is subtraction. Subtraction undoes addition by taking away a number from the sum to return to the original value.
The types of addition include associative (changing the grouping of numbers does not change the sum), commutative (changing the order of numbers does not change the sum), and identity (adding zero to a number gives the same number).

Subtraction involves taking away a number from another number, while addition involves combining two or more numbers to find a total sum. Subtraction results in a smaller number, while addition results in a larger number.
Subtraction is the inverse operation of addition. Adding a number and then subtracting the same number will bring you back to the original value.
