Introduction to Algebra II - At Right Angles Pullout

This article is Part II of the series ‘Algebra – a language of patterns and designs.’ The approach is based on the perception of algebra as a generalisation of relationships.

In Part I, we introduced the ideas of variable, constant, term and expression via numerical patterns. Various operations (addition, subtraction, multiplication) involving terms and expressions were also studied.

Now in Part II, we revisit the usage of words such as variable, term and expression and concepts and operations involving terms and expressions in the context of geometric designs (line designs, 2-D designs, 3-D designs).
