How is math used in everyday life? This is a big question requiring a big answer. It is amazing at just how many uses are significant. Math is everywhere, all the time, and constant as we move on. Yet, few of us actually need to do any calculations beyond the basics. Knowing is has invaded almost everything is important to know. A. Medicine. CAT scans and MRI scans require deep math at their basis. Modeling of DNA and sequencing of genes use much math. The origin was with SONAR, where the computer was the human brain, i.e. operator. It is well past that now. The mathematics is called tomography. It takes the scans and uses them to reconstruct the complex images within the brain or body. B. Transportation. Routing of vehicles (trucks and aircraft, etc) to maximize efficiency of costs use deep math. Involves one of the most difficult math problems called “The Traveling Salesman Problem.” It is still open, i.e. unsolved. C. Electronics. Use the math of all of electromagneti
