Please explain adding and subtracting Integers

457 views

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.

Not sure where you are located but where I’m from we don’t write the + sign in front of positive integers, only for negative integers. That might be a source of confusion.

So

29 – 59 = -30, because:
29 –
59
_____

9 – 9 is 0, and 2 – 5 is -3.

It might be hard to understand in text form like this, I recommend this free resource for learning math. You can start from the VERY beginning of numbers and work your way up at your own pace:
