Design is thinking made visible. That's why your Powerpoint presentation reveals so much about your way of thought. "Wait, design is not about creativity?" - "No!"
Design is about typography, color psychology, geometry, density, balance, symmetry, hierarchy, contrast, repetition, proportion, and white space. One can immediately see how well your thoughts are structured in the simplicity and clarity of your slides. Steve Jobs and Elon Musk use the power of design, too.
By the way, Powerpoint has a lot of functions that help you with slide design and even formulas.
In module 2 you will visualize your thoughts easily with Powerpoint.
