Arithmetic
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Arithmetic is a simple branch of mathematics. It has to do with calculations that we make in everyday life. All calculations can be done with four basic actions: addition, subtraction, multiplication and division. Arithmetic also includes more complex actions which are made from the four basic actions, such as: raising to a power (done with many multiplications), fractions and percentages (which are results of division). Arithmetic is also the main part of number theory which deals with relations between numbers, for example: which number is divisable by another (the other can be multiplied by something to give the first). It is the basis for calculations in all other branches of mathematics.
