Answer:
The answer is 30.
Explanation:
All you have to do is subtract 20 from 50, which is 30, and keep the sign of the greater number, 50. The answer will end up being 30.
-20 + 50 = 30
There really isn't a way to simplify a whole number, unless you wanted to divide it down. I which case you could divide 30 by 2, 5, or 6.
