What are you studying in Geography right now? :D I can help with that. Also integers and Geometry.
I'm going to start with integers. Tell me if this helps you at all.
When it comes to adding integers, I like to think of negative integers as empty flower pots, and positive integers as bags of soil. Say you're trying to solve something like this: -4 + 5. So, that's four empty flower pots, and five bags of soil. You fill in the four empty pots with four whole bags of soil. This leaves one bag of soil left over. So, -4 + 5 = 1.
When it comes to subtracting integers, think of a bank account. Say we have the problem -11 + 5. Think of a bank account that you have. Say you have five dollars in the account, but then you spend eleven dollars through your credit card. That means the five dollars get spent, and then you owe six MORE dollars because you did not have those six extra dollars to spend. So, -11 + 5 = -6.
When it comes to multiplying (OR dividing...the same rules work for dividing) integers, all you have to do is ignore the negative or positive value for a moment, then multiply or divide the numbers as usual. Multiplying or dividing two numbers with the same sign (both positive or both negative), the answer will be a positive number. If the two numbers have different signs, then the answer will be negative.
If you remember all that, then all you have to do is remember some of the other rules--like if you see something like this: 5 - (-7). Since there is a subtraction sign right next to the negative sign of a negative integer, that makes the negative integer turn into a positive one, thus making the problem change to 5 - 7.
Like I said before, tell me if that helped...if not, please tell me what you're having trouble with and I'll try to help. ^_^
