Basics: Let's start with arithmetic operators

In this first introduction to operators, we’ll introduce the operators you are most likely familiar with: arithmetic operators with two operands. Those operators assume the operands are both numbers.

+ performs an arithmetic sum:

 1 + 2 //3

Then we have the subtraction operator (-)

4 - 2 //2

The multiplication operator *:

4 * 2 //8

The division operator /:

4 / 2 //2

And the remainder operator:

4 % 2 //0

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. Launching May 21, 2024. Join the waiting list!
