What numerals can you add together?

Any values smaller than the numeral being added to.

e.g. You can add I, V, X, or L to C

Do not use larger numbers to add:
You will create a subtraction!

27

Which numerals can you subtract from another?

The "One" value immediately before the value being subtracted from.

Do not use numerals any farther away, such as "IC" for 99.
