Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

Nowadays 999 when converted into Roman numerals is now considered to be CMXCIX which does not quite easily lend itself for the purpose of arithmetical operations but the ancient Romans would have probably worked out the given three calculations as follows:-
IM+DCCLXXVII = MDCCLXXVI => (1000-1)+777 = 1776
DCCCCLXXXXVIIII+DCCLXXVII = MDCCLXXVI => 999+777 = 1776
DCCCCLXXXXVIIII-DCCLXXVII = CCXXII => 999-777 = 222
QED
What two numbers add to 4 yet their product is 3.4375 showing work with answer?
Let the numbers be x and y:-
If: x+y = 4 and xy = 3.4375
Then: y = 4-x and x(4-x) = 3.4375 => 4x-x^2-3.4375 = 0
Solving the above quadratic equation: x = 2.75 or x = 1.25
Therefore the numbers are: 2.75 and 1.25
Check: 2.75+1.25 = 4 and 2.75*1.25 = 3.4375
