Donkey Kong Jr. Math

For DK Jr Math (NES), there is only one score so far on the page. In my pal-version, I have those scores here:

Highscores (+)

(group:) +-x: Exercise

00 + 00
000 - 000
0000 + 0000
0000 - 0000
0 x 0
000000 + 000000
000000 - 000000
000 x 00
00 : 0

I know this looks quite strange, here a photo of how it looks in the game^^
