Arithmetic is the study of numerical quantities. At least a basic understanding of arithmetic is fundamental in the study of algebra and many other mathematical studies.
Basic Operations[edit | edit source]
There are four basic operations one can perform on different numeric quantities (as well as other mathematical objects which you will encounter later). These are:
- addition
- subtraction
- multiplication
- division
Equals[edit | edit source]
It is also important to understand that the equals sign (in this book, '' ) means that the things on both sides are of equal value, and that is not an operator.
When you see an sign, say to yourself Same value, different appearance.
