You don't round the theorem, you round the final result you obtain.
Rounding a number is when you take a number and "bump it up" or "bump it down" to a nearby and "cleaner" number. A number can be rounded to any place value you want.
so, if the final result is decimal number, you round it up to nearest whole number, or tenths, or hundreths
