Well, no, but I like the thought. Tell you what, if all conditions are met (including that 2 + 2 = 11), thenit might as well be considered the right answer.
However, intended answer is this:
2 + 2 = 11 is true in ternary (base3) numeral system
Such is a system when you use just 3 numbers for counting, unlike common 10. In ternary system counting from 0 to 10 looks like this:
0, 1, 2, 10, 11, 12, 20, 21, 22, 100, 101
So, naturally, in this system 2 + 2 = 4, you just write 4 in a different way. The fun part is that it is generally assumed that '11' means 'eleven' while it's just a notation. Little trick.
