Question

Little Lucas invented his own way to write down negative numbers before he learned the usual way with the minus sign in front. Counting backwards, he would write:

3, 2, 1, 0, 00, 000, 0000,... What is the result of 000 + 0000 in his notation?

Answer 1

000 + 0000 = -2 + (-3) = -5

Answer 2

000 + 0000 = -2 + (-3) = -5

Explanation:

3, 2, 1, 0, 00, 000, 0000, .....

So 00 = -1, 000 = -2, and 0000 = -3, and it follows that 000 + 0000 = -2 + (-3) = -5.
