How do you make 1480 if the only numbers you have are 3 and 7?
As long as you are able to repeat numbers, one way of doing so
is by saying:
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 +
7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 +
7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 +
7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 +
7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 +
7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 +
7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 +
7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 +
7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 +
3 + 7 + 3 + 7 + 3 + 7 + 3 + 7 = 1480
