Nrich Maths Problem Make 100


Our learning intention was to make 100 using the digits 1 to 9.
First we did 5 times 8 which made 40 so we needed another 40 so we did 6 times 7 and the answer was 42 and we added them together which gave as a total of 82.
We still needed 18 so we can get 100 so we did 9 times 2 and it equaled 100.
We still had the digits 1,3 and 4 left so we did 1 plus 3 which made 104 then finally we only had another 4 left so we did 104 minus 4 and we got the answer 100.
We didn't use any division.
