When counting numbers on a dice
there’s always one number you can’t see
If 5 is on the right, a 1 on the left
then the bottom under, may be a 3
A simple trick
to guarantee if its really true
is if, the side facing up
is clearly the number 2
Unless, the value fixed
at the top is a 6
then, you’ll know for sure
the number under, out of view
is most definitely a 4
