A notation is the formal structure of an instruction according to the rules of the programming language used. It is the description of the elements used in the programming language.

There are various notations, including Hungarian notation, Polish notation, reverse Polish notation, scientific notation and positional notation. The Hungarian notation is about the representation of the variable type in the variable name. For this purpose, the data type is appended to the variable as an abbreviation. Thus the programmer knows which data type is assigned to the variable. The Polish and the reverse Polish notation are notations for arithmetic operations. Both differ between the linkage ofoperand and operator.

Scientific notation is a mathematical notation used mainly for very large and small numbers and uses the potential representation. The digit is represented as a number and a power of ten.

And the positional notation corresponds to our numerical notation of a decimal number with ones, tens, hundreds, and so on. So the digit 234 has two hundreds, three tens and 4 ones.
