Let us first convert the Roman numerals into Hindu-Arabic numerals.
When a Roman numeral with the larger value is on the left, we add the values together and when it is on the left, we subtract the values.
∴ XLVI = (50 - 10 ) + 5 + 1
= 56 - 10
= 46
LXX = 50 + 10 + 10
= 70
∴ XLVI + LXX = 46 + 70 = 116
But, 116 = 100 + 16 = C + XVI = CXVI.
∴ XLVI + LXX = CXVI
