Many articles say you should pay off you credit cards in full every monthly billing cycle. However, I thought credit is built by paying interest. So say you have a $1000 credit for one credit card. I now make $250 in purchases using that card and I pay off $100 for that month. The company sees I made a payment, they add interest to whats remaining and my credit score improves since I have made a payment for that month.

Now I owe $150 + interest and I leave that $150 for the next monthly cycle. I will have a minimum payment due but now I will pay it off fully and I don't make any purchases using that card for that month. So the following month after that I will have borrowed $0 in credit and therefore that should mean I don't build any credit history, correct? 

I could be completely wrong but I just want to be sure how I can build credit properly. Another hypothetical is say I have made purchases in the same month using one credit card, paid it off then bought more stuff and I do not pay this amount off. This then transitions over to the next month with interest? 

Need recommendations on quality bicycle headlights. I have a giant escape 2 (2019) and it has a 31.8 alloy handle bar. What are some great headlights that provide long battery life, high lumen count and affordable pricing. I am not against higher prices headlights but they should be worth the price. Also I was thinking the cateye amp 1100 lumens, let me know what you think of these.

0x0E - 0xFF gives you a +15 in signed decimal integer but can you show me the steps to subtract in hex. It requires you to carry from the right, maybe I'm wrong.

In Adobe Acrobat reader, I would click on hyperlinks (URLS) and the default browser would open in Edge. Is there a way to change it to chrome? I tried to find it online and the result just showed me how to make my default pdf opener as chrome which is not what I want. 

I tried to record a lecture instead of a game but it should work in any instance. My internal audio was not recording until I turned my mic on. The issue is when my mic is on, both internal and external sounds and audio is recorded. I don't want external audio to be captured when I do the recordings. Is there a way I can fix this because if I didn't turn my microphone on, the recording should capture internal audio. However, it does not. Please let me know if you guys have any solutions regarding this issue and let me know if you need any clarification. Thanks.

I am already in college and planning to do basic training in the summer.

My major is computer engineering and so keeping that in mind, I would like to get the best MOS that pays well. Most importantly, the MOS I choose should be able to give me the most experience I need so that I can use it when applying for civilian jobs.

What is the difference between the the army and the national guard. If I have completed a semester of college, but I have one more to go, can I go to basics in the summer? Last question, should I join my ROTC program at college or should I become a national guard? Thank you for taking the time to answer my questions. If you answer any specific question please copy paste the question from here so that I know which question you are trying to answer. Thank you.
