:First we wrote down all the numbers from one to fifteen.
:Then we looked at the numbers and sorted out which ones add up to fifteen.
But then,we didn't read the second question so the numbers we put in were wrong.
So then we put in eight and seven and it worked!
We looked at the third card and saw which number added up to twenty and it was thirteen.
We looked at the fourth card and saw which number added up to twenty-three and it was ten.
We looked at the fifth card and saw which number added up to sixteen it was six.
We looked at the sixth card and saw which number added up to eighteen and it was twelve.
Finally, we looked at the seventh card and saw which number added up to twenty-one it was nine.
Our answer is:
8,7,13,10,6,12,9.
