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 ...
This shows that the statement is true for these examples, but to prove that it is true all the time we must use algebra. Write the first of the two even numbers as \(2n\), where \(n\) is an integer.
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, ...
