Thus, for instance, exercises on the use of graphs are given, some at quite an early stage; there are problems to show the application of algebra to geometry, mensuration and elementary physics ...

A string of numbers and letters joined together by mathematical operations such as \(+\) and \(-\) is called an algebraic expression, for example \(r + 2s\). Suppose that \({g}\) is the cost of ...

Suitable for senior undergraduates and beginning graduate students in mathematics, this book is an introduction to algebraic number theory at an elementary level. Prerequisites are kept to a minimum, ...

Parsing algebraic expressions is always a pain ... If that was too fast, read the post which has a nice flowchart and an example step-by-step parse of 1+2-3*4+5/6^7-8*9. Towards the bottom ...
