Kindergarten (from German, which literally means "garden for the children") is a preschool educational approach traditionally based on playing, singing, practical activities such as drawing, and social interaction as part of the transition from home to school.

The first such institutions were created in the late 18th century in Bavaria and Strasbourg to serve children whose parents both worked out of the home.

The term was coined by the German Friedrich Fröbel, whose approach globally influenced early-years education.

Today, the term is used in many countries to describe a variety of educational institutions and learning spaces for children ranging from two to seven years of age, based on a variety of teaching methods.

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.

A fraction (from Latin ', "broken") represents a part of a whole or, more generally, any number of equal parts.

When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

A common, vulgar, or simple fraction (examples: and 17/3) consists of an integer numerator displayed above a line (or before a slash), and a non-zero integer denominator, displayed below (or after) that line.
