Subtraction is a mathematical operation that represents the operation of removing objects from a collection.

It is signified by the minus sign (−).

For example, in the picture on the right, there are 5 − 2 apples—meaning 5 apples with 2 taken away, which is a total of 3 apples.

Therefore, 5 − 2 = 3.

Subtraction represents removing or decreasing physical and abstract quantities using different kinds of objects including negative numbers, fractions, irrational numbers, vectors, decimals, functions, and matrices.

Multiplication (often denoted by the cross symbol "×", by a point "·", by juxtaposition, or, on computers, by an asterisk "∗") is one of the four elementary, mathematical operations of arithmetic; with the others being addition, subtraction and division.

Addition (often signified by the plus symbol "+") is one of the four basic operations of arithmetic, with the others being subtraction, multiplication and division.

Educational games are games that are designed to help people to learn about certain subjects, expand concepts, reinforce development, understand a historical event or culture, or assist them in learning a skill as they play.

Game types include board, card, and video games.

Division is one of the four basic operations of arithmetic, the others being addition, subtraction, and multiplication.

The division of two natural numbers is the process of calculating the number of times one number is contained within one another.

For example, in the picture on the right, the 20 apples are divided into groups of five apples, and there exist four groups, meaning that five can be contained within 20 four times, or.

Division can also be thought of as the process of evaluating a fraction, and fractional notation (and) is commonly used to represent division.
