As my birthday approaches I start to collect leaves - a little bizarre perhaps, but I enjoy it!
On the first day of the month I collect 1 leaf, on the second day I collect 2 leaves, the third day I collect 3 leaves, and so on.
By my birthday I will have collected 276 leaves altogether. On which day of the month is my birthday?
