ants go marching two by two, they all suffocate in a puddle of wet glue
ants go marching three by three, 2 fall down and one has to pee
ants go marching four by four, 3 get steped on one gets caught in the door
ants go marching five by five, 5 are murdered...how many ants survived?
Thirty-nine (39) ants survived.
Because it says, for example three by three, it means it is X numbers
wide and X number deep. So, All the one by one ants die as do the two by
two. Three by three, which totals 9, has 2 gone. One has too pee
but is still there. Out of Four by Four ants, totaling 16, four die off.
Leaving 12. Five ants by five ants are 25 ants, 5 are killed. Thus if you
add remaining ants you get.....39.
(red ones were killed)
