Explanation:

Step1: Recall Roman - numeral symbols

Roman - numeral symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1000.

Step2: Convert 2014

2014 = 2000+10 + 4. 2000 is MM, 10 is X, and 4 is IV. So 2014 = MMXIV.

Step3: Convert 1076

1076 = 1000+70 + 6. 1000 is M, 70 is LXX (50 + 10+10), and 6 is VI. So 1076 = MLXXVI.

Step4: Convert 592

592 = 500+90 + 2. 500 is D, 90 is XC (100 - 10), and 2 is II. So 592 = DXCII.

Answer:

a. MMXIV
b. MLXXVI
c. DXCII
