I will be doing a scribe on the first lession we did.
(-6) + (+9) =
Breaking this question down in to words it would have said.
Owe 6 and Have 9 =
The reason this is what it is, it's because the - means that it's Owe and the + means that it's Have.
The job of the brackets these ( and ) are to seperate the numbers.
Finally the + in the middle stands for and it separates the number to tell you that they are what need to be added.
