Hash sign/symbol on the Macbook

I had to get a new notebook yesterday after spilling a cup of green tea on my Macbook pro. I’ve spilled some liquids on it before, but this time the keyboard and trackpad stopped working completely.

After using the Macbook for a few minutes, I realized that it doesn’t have a hash symbol, also known as the pound sign where my Macbook pro did indeed have it as Shift + 3.

I managed to figure out that in order to get a pound sign/hash symbol, you have to press Alt + 3
