Ok, the only way I can see this even working is kind of sketchy, but here goes:

Let’s say that each of these zeroes are an object. so here, we have 5 zeros. Each of them counts as 1 object.

120 has 3 numbers: 1, 2 and 0. Let’s say each of these numbers is their own respective quantity. So:

1 zero = 1 unit (1), 1 zero + 1 zero = 2 units (2), and for the last number, 1 zero – 1 zero = 0 units.

So we have used 5 zeroes and made the number 120.
