Back Fence Puzzle

I’m a retired guy living with my friend in the condominium next to the Masjid Ibrahim in the Oak Hill neighborhood of Austin, Texas. I have enjoyed seeing the families attend for Friday prayers and other occasions from our backyard deck. Just for fun I have placed a puzzle on the back fence facing the parking lot to challenge young scholars who are interested. If you solve the puzzle you can post your answer as a comment to this post. If you want to be acknowledged, leave a name or nickname and I can put the solvers on the fence as well.

Last week’s puzzle: If AA + PC = EA, then what does 23103 spell?

Answer by Gary: PEACE

This week’s puzzle: If PY + A = PH, then what does 43991 spell?

Answer by Gary: HAPPY; though could also be HYPPA which is some kind of bug.

Adults may identify the location of the photo below and I will buy lunch for the first to do so.
