Number Conundrum

Doing this was challenging but the number line strategy
had helped me with getting the missing answer
either a negative answer or a positive answer.
The name of this game is called number conundrum.
To play this is really simple cause all you need to do
is to work from top to bottom, using the clues given.
The thing that I learnt from this activity was that the
top number that is given would give you a clue to the
next number under it.
