As we can see, there are some steps that must be followed. These steps are in a specific order, even though some of the steps could be rearranged.
but we need to keep in mind that the order of some steps can probably be changed but you cant move them far away from where they should be. For example, you cant make the tea without boiling the water, as a result we will end up drinking a cup of iced water which is totally different from your initial goal.
So, making a cup of tea is a part of alogorithm because algorithm is a set of instructions for solving problems.
