2 shoes 10x3=30 // 2 shoes + 2 kittycats - 10+5+5=20 // 1 kittycat + 2 hornbuckels + 2 hornbuckels = 5 + 4 + 4 = 13 // And... 2 shoes + 1 kitty cat + 1 hornbuckel = 10 + 5 + 2 = 17 I totally hated these pumped up math word games in school, I'd much rather look out the window at the clouds and shoot spit wads... lol
