A comment on Making any integer with four 2s (2025). Parent comment
It would be like if we had a stylistic convention that you can drop the second number in an addition and it becomes 1. So "6 +" means "6 + 1."
Now I can trivially make any number, but I'm just 'exploiting' a convenience feature of the notation:
0 = 2 + 2 - 2 - 2
1 = 2 + 2 - 2 - 2 +
2 = 2 + 2 - 2 - 2 + +
Etc
