Why should you study chemistry?
Chemistry is the basis of all other sciences. Biology is simply chemistry at a cellular level. Physics is the study of how matter which is made up of atoms of different elements interacts with the environment through the understanding of space and time. Understanding chemistry gives you a different view of how the world works and why everyday things like the color, sound, the heat you feel one you get inside your car that's been sitting outside for 8 hours, etc. have a scientific explanation.
What is Calculus?
Not only the basis for Differential Equations, Perhaps a subject that is sometimes hard to visualize by the nature of its problems, it is quite fascinating to work through a kilometric calculus problem so that at the end everything cancels out and it is qual to 1. LOL
What is Algebra?
Algebra is the basis for more elevated math such as Calculus and Differential Equations. As an engineer, great algebra skills will make more complicated math subjects easier to understand and easier solve. Algebra is all about manipulation of functions and mathematical expressions.
