Klaas Jan Damstra wrote about it:

“Addition is one of a series of designs with a mathematical theme. With three nearly identical pieces in a frame, 13 moves are needed to get the first piece out. As the solution level is 13.2.1 both disassembly and assembly should not be too difficult. Pelikan did a fantastic job on producing this design. Two beautiful versions are available; the first is made of purpleheart and apple tree, the second of merbau and apple tree. I hope you'll find this puzzle fun to play with.”
