I'm considering a career as a Linux sysadmin, and I'm wondering how much math knowledge is actually necessary to reach a senior level. Do I need advanced math skills similar to what a graphic designer might use, or is the math required more basic? I'd appreciate a general overview of what to expect. Thanks!

Honestly, I was terrible at math in college and still managed to be a decent sysadmin! It really doesn’t pop up often unless you're doing specific calculations, but even then, you have tools like subnet calculators to help out. Focus more on logic and understanding concepts rather than crunching numbers.
You don't really need advanced math skills to be a senior Linux sysadmin. Most people I've talked to say basic school algebra is more than enough. In fact, a lot of us just rely on calculators for anything more complicated. Honestly, the myth that you need to excel at math in IT is pretty widespread but not true.
I've been a UNIX/Linux admin since the 90s and I can confirm, math isn't my strong suit either! Basic numeracy plus a calculator is all I really need. Sure, it's a bonus to have some general understanding of math concepts, but you're not going to be calculating complex equations as part of your job.
So, it really depends on what your job involves. If you're just troubleshooting, you might not need to do math at all. But if you’re working with storage or making budget estimates, you might need to know a bit more. However, using calculators and software can cover most of that! Just focus on having solid basic skills to get by.
And yeah, using Excel for budgeting or figuring disk space is super common. No need for advanced math!

Math isn't really a big part of IT anyway. Knowing some logic and how networking works is what really counts.
