Answer 1

Answer: (A), (D)

The correct options are
A When a Roman numeral with the larger value is on the left, we add the values together.
D When a Roman numeral with the larger value is on the right, we subtract the values.

When a Roman numeral with the larger value is on the left, we add the values together.

For example, XI = 10 +1 = 11.

When a Roman numeral with the larger value is on the right, we subtract the values.

For example, IX = 10 - 1 = 9.

These are rules that are used when writing Roman numerals.
