Test 1

r1 = [53:LIII]
r2 = [1949:MCMXLIX]
r3 = [34:XXXIV]
r4 = [1949:MCMXLIX]
result = r1 + r2/r3 = [53:LIII] + [1949:MCMXLIX]/[34:XXXIV] = [110:CX]

[53:LIII] and [34:XXXIV] are equal: false
[53:LIII] and [1949:MCMXLIX] are not equal: true
[1949:MCMXLIX] and [1949:MCMXLIX] are equal: true
[34:XXXIV] and [1949:MCMXLIX] are not equal: true

Test 2

[1963:MCMLXIII] + [56:LVI] = [2019:MMXIX]
[2001:MMI] - [33:XXXIII] = [1968:MCMLXVIII]
[53:LIII] * [33:XXXIII] = [1749:MDCCXLIX]
[2001:MMI] / [33:XXXIII] = [60:LX]
