Addition Clock (7) - Game Information

@ Wentu:

Never thought of it that way. To me, the thinking was that the number in the middle (in this case, the 7) is what you add to the outer number on the clock (in this case, 5) to get the answer, which is outside of the clock (12).

So you go around the clock, 1+7=8, 2+7=9, 3+7=10, and so on.

So in a sense, the problem is really to solve the equation N+7=12.

I guess it does force you to think a little differently to find the answer, but that's not always a bad thing.

Hi tickman
this time I have a feedback by my son. He's veeeery young but somehow obsessed with numbers. He, and me too, find confusing the fact that in a series like this, the question is 12, the answer is 5, but in front of the number you got a "+". I am telling him "12 minus 7 equals .. ? " and maybe he answers "5, but there is a plus before 7".

Asking 12 and writing "+7", the natural answer that comes to my (and his) mind is "19".
does that makes sense ?

anyway, very useful series for kids
