Answer 2

Under what naming convention?????
There exist two naming convention for the naming of numbers the American (use primarily in US) and the British (use nearly worldwide). In both the American and the British systems, a one followed by six zeroes is one million and the the names of the numbers are constructed with Latin prefixes attached to “-illion”.
In the American system the Latin prefix tells how many groups of 3 places zeros are in the written number, not counting the first group of three (the one which represents numbers up to 999). In the other system, the Latin prefix tells what power of a million the number is. For example, “bi-” is from the Latin for “two”. To the Americans, that means adding 2 more “000” groups to “1,000,” so one billion = 1,000,000,000. In the other system, a billion is a million to the second power, that is, 1,000,000~2, so a billion = 1,000,000 × 1,000,000 = 1,000,000,000,000. The discrepancy between the two systems grows as the numbers the prefixes stand for get bigger.
So we have that:
American system 999 trillion + 1 trillion = 1 quadrillion
British system 999 trillion + 1 trillion = 1 billiard
