5 Math Skills Every Programmer Needs

TL;DR

Most software engineers need math skills for problem-solving and coding interviews.

Transcript

Most Software Engineers have a degree in Engineering or Science. Do you know why? There are 2 main reasons for this. One, Engineers can generally think logically. Two, Engineers are good at Math. One of the major reasons I was able to get a job at Google without a Computer Science degree is because I am above average at Math. Now, I can not teach y... Read More
