Hello Sascha, although I detested maths at school, I enjoyed this one:
One horse = 10
One horseshoe = 2
One cowboy boot = 1
Two cowboy boots = 2
First row: 10 + 10 + 10 = 30
Second row: 10 + 4 [<- 2 x 2]+ 4 [<- 2 x 2] = 18
Third row: 4 [<- 2 x 2] – 2 [<- 2 x 1] = 2
Fourth row: 1 + 10 x 2 = 11 x 2 =
21
If this is the correct solution, I will revise my opinion concerning maths.
