I am trying to start again with math, giving it a second shot after i completly gave up on math for about 10y. I looked up multiple cheet sheets and rules, but they all say different things. My problem especially +29 – +59. The rule thing i got from the internet says + – + = larger integer’s sign, but then another tutorial said well if you reverse + and -, then you can get the answer that way, but they are 2 different answers. And i’m confused too about what, like what’s the point of doing the operations if we can just change whatever symbols we want, but then we do but nothing matches as the result so i’m just confused.
I just don’t get it, none of the rules match and in my head none of it even makes any sense. So i feel like i need to memorize the rules, but there are no rules. Pls help, i started crying due to the fustration because now i remembered why i despised math so much.
Update: I started being able to complete operations, even of 5 in a row. Thank you all! Ended up dropping tje unecessary + and just – – = + idk, but i’m doing it.

For addition, the order of the numbers doesn’t matter. (+29) + (+59) is the same as (+59) + (+29). The sign of the larger integer will carry through. But for subtraction, the order is important. This is because the – changes the sign of the second number only.
It may help you to think of subtraction problems as addition problems where the sign of the second number is the opposite of what it was in the original problem. So in the case of (+29) – (+59), change the problem to (+29) + (-59). Then the rule of the largest integer still works.
