Dear Tim,
We are students at Hermann Middle School. We are in
the 7th grade. We worked on the Get Ten. We had to
get the number 10 on the calculator using the keys
that were given to us in the clue. We had two
separate groups working on this problem. We each came
up with something a little different.
Group 1: We started out by writing down all the
numbers we had to use and could use in the form of a
table. We had to use three twos and a minus sign.
Since we had to use a minus sign, we decided we had to
get over ten. We decided that the first number we
would get to was twelve. We started out by
multiplying one of the "must" twos with the "may" 6 to
get twelve. Then we realized that we had to use two
more twos. So, we added a "must" two to the product.
We then minused another 2 to get 12 again. Then we
minused another 2 to get 10!
Group 2: First we read through our cards and wrote
down all the numbers we had to press and all the we
could press in different groups on the paper. We then
experimented with different equationsguess and
check. We started with 2x2x2+6 and realized that it
was way too much. We had used all of our numbers and
we still had to use the minus sign. Then, we thought
we should subtract instead of multiplying as much. We
did some more guessing and checking and finally came
up with 22+6x22=10!
Thank you so much accepting our last entry to the
website. We really enjoy doing your problems because
they are fun and challengeing. We also like working
together.
