Ah I see, that was redundant. Thank you
Another silly operations error. I seem to make a lot of those. Anything you would recommend that could reduce the amount I make?
Gratefully,

So like, this might sound a little odd, but my suggestion is to just whenever you make a mistake - don't just figure out what you did wrong, do the question again from scratch. Hell, if you know you're making mistakes like these, don't check your working to see what you did wrong (because hell, even for me it took me a while to see what you did wrong, and I'm not biased by your own thinking of, "but I did everything right?" that everyone has when analysing their own questions or proof-reading their own essays), just do the question again blindly and see if you get the same answer.
I had a teacher who used to say, "practice doesn't make perfect - perfect practice makes perfect". And so, if you're constantly making silly little calculation errors, that's not perfect practice. But if you make sure that every question you do, you've done it at least once without making this little mistakes, you might be able to slowly ease them out of your own thinking so that you don't make them in an exam. Hell, if you have time in an exam, find the questions worth the most marks and do them a second time to see if you get the same answer. Can't hurt, as long as you're not doing it on your actual exam booklet (you should be able to get spare paper in your exams)
I have no proof that this will work, but tbh the only other advice I have is, "make sure you double check your working, always be careful, read every line twice, etc.", which we all know isn't that effective.
