WIKI: Subtraction (also called "takeaways") is one of the four basic arithmetic operations; it is the inverse of addition, meaning that if we start with any number and add any number and then subtract the same number we added, we return to the number we started with. Subtraction is denoted by a minus sign in infix notation.

The traditional names for the parts of the formula

c − b = a

are minuend (c) − subtrahend (b) = difference (a).

Counting is the mathematical action of repeatedly adding (or subtracting) one, usually to find out how many objects there are or to set aside a desired number of objects (starting with one for the first object and proceeding with an injective function from the remaining objects to the natural numbers starting from two), or for well-ordered objects, to find the ordinal number of a particular object, or to find the object with a particular ordinal number. Counting is also used (primarily by children) to demonstrate knowledge of the number names and the number system. Sometimes the term counting is used to mean the same as enumeration, i.e. finding the number of elements of a finite set.)

Counting sometimes involves numbers other than one; for example, when counting money, counting out change, when "counting by twos" (2, 4, 6, 8, 10, 12…) or when "counting by fives" (5, 10, 15, 20, 25…).

Wiki: Subtraction (also called "takeaways") is one of the four basic arithmetic operations; it is the inverse of addition, meaning that if we start with any number and add any number and then subtract the same number we added, we return to the number we started with. Subtraction is denoted by a minus sign in infix notation.

The traditional names for the parts of the formula

c − b = a

are minuend (c) − subtrahend (b) = difference (a). The words "minuend" and "subtrahend" are uncommon in modern usage^{[citation needed]}. Instead we say that c and −b are terms, and treat subtraction as addition of the opposite. The answer is still called the difference.

"Mental arithmetic is elementary arithmetic performed in the head, for example to know that 100 − 37 = 63 without the use of a calculation aid, such as a sheet of paper, a slide rule, or a calculator. It is an everyday skill. Extended forms of mental calculation may involve calculating extremely large numbers, but this is a skill not usually taught at the elementary level."

WIKI: Word problems commonly include mathematical modelling questions, where data and information about a certain system is given and a student is required to develop a model. For example:

1. Jane has $5 and she uses $2 to buy something. How much does she have now?
2. If the water level in a cylinder of radius 2 m is rising at a rate of 3 m per second, what is the rate of increase of the volume of water?

These examples are not only intended to force the students into developing mathematical models on their own, but may also be used to promote mathematical interest and understanding by relating the subject to real-life situations. The relevance of these situations to the students is varying. The situation in the first example is well-known to most people and may be useful in helping primary school students to understand the concept of subtraction.
