• Math is a way to analyze complex problems and the world around you. It helps your brain connect pathways and come to quicker solutions by breaking down a problem to its most basic ingredients (first principle thinking). It's only when you're able to break down a problem to its most fundamental components, you're able to see the solution. In math, we do this by using an abstract language (numbers)

Example:
8 + 7
10-8=2
7-2=5
10+5=15
