A gray cat face with pointed ears, green eyes, a pink nose and black whiskers. The whiskers and nose come together at the end, which makes the reveal fun.

Numbers go up to 20, but no problem bridges ten. Additions like 12 + 5, 14 + 3 or 11 + 6 keep the ones under 10, and subtractions like 17 − 4 or 19 − 6 never need to break into the ten. Answers that land exactly on a ten are allowed, so 7 + 3 = 10 and 13 + 7 = 20 appear, while 8 + 5 or 13 − 5 do not. The idea to take away is that 15 + 3 works just like 5 + 3 with a ten in front.
