ABSTRACT
This chapter aims to understand basic operations in algebra and seeks to understand factorisation. Algebra is one of the most fundamental tools for engineers because it allows them to determine the value of something given values that they do know. Although the types of problems that mechanical, chemical, civil, environmental, electrical engineers deal with vary, all engineers use algebra to solve problems. An example where algebra is frequently used is in simple electrical circuits, where the resistance is proportional to voltage. Variables are labels for numbers and measurements students do not yet know. Algebra lets they use these variables in equations and formulae. A basic form of mathematics, algebra is nevertheless among the most commonly used forms of mathematics in the workforce. An engineer uses mathematics all the time – and in particular, algebra. Becoming familiar with algebra will make all engineering mathematics and science studies so much easier.
