Step-by-step explanation: To solve this problem, we can first start by rewriting the problem. When we add a negative, that's exactly the same thing as subtracting so we can make the problem easier to understand.
18 + (-30) → 18 - 30
To find the answer to this problem, let's first find out how many jumps it get's to 0 from 18. It would take 18 jumps and there is 12 jumps left over. Then, we would subtract 12 from 0 and we would get -12 as our answer. Therefore, 18 + (-30) = -12.
To solve this, keep in mind these rules. The rules for "+" and "-" are as follows:
+ and + = +
- and - = +
+ and - = -
- and + = -
All you have to keep in mind is that positive values and positive values are always positive; negative and negative values are always positive; positive and negative values are always negative!!
We removed the brackets!
As I said before, positive and negative values are always negative!
