We think that we have found two solutions for the first question:
123 / 3 = 41 12 / 2 = 6 1 / 1 = 1 or 321 / 3 = 107 32 / 2 = 16 3 / 1 = 3
We think that there is no solution for the question for 1, 2, 3, 4. We kept trying different number orders and tried to divide them by 4, and some of them worked, but when we moved on, the division equation didn't work. A rule that we found was the number that we were dividing had to have a pattern that goes odd, even, odd, even. The reason we think this is because it has to be divided by 4, then divided by 2. Odd, even (divide by 2), odd, even (divide by 4).
We don't think that there will be any other numbers that work above 4 because since we can't find any solutions for 4, then it will always come back to 4 so it will never work.
Thanks for reading!
