The first thing you should do is draw this or get a program to do it. I use desmos. It is included. The graph shows one complete cycle every 2*pi intervals (or 360 degrees.)
You will find no lower value that y = - 1 (nor any value greater than y = 1)
7-18= a negative number. We know that it'll equal a negative number because the minued(7) is less than the subtrahend(18), which results in a negative number (if both are positive).
We can make an addition problem from this. We can have 18 turn negative and 7 stay positive, and we'll get the same answer.
7+-18=7-18
7-18=7+-18=11
There should be only be one step necessary
