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. ;)

sadly the perfect answer. but i find it very interesting how your eyes / brain cheats you because it is trying to solve this calculating on the easiest way. not differentiate between 1 or 2 shoe /horseshoe or even the calculation rules.

Yes, the last row is also sneaky because x and / take priority over - and +

I can do the maths I need to but all the algebra and trigonometry lost me.
