Adding Demand Curves 1 - Horizontal Summation

Hi Everyone! In this video I address finding the market demand diagram from individual demand curves. This skill is often called Horizontal Summation – or alternatively - simply adding up demand curves. In particular in this video the example we look at has a (so-called) 'kink'. This is the first of two videos on this topic - the next to come looks at the algebraic representation of the work done in this video. Hope you are all well!!
