  1. Fay’s Nines Reflection

    November 7, 2018 by Joshua Whan

    The task for Fay’s Nines was to use the numbers from 1-9 to make 999 by adding them using vertical addition.

    When we started of with the problem  we kind of just shuffled around the numbers and see what it equalled but that kind of got us nowhere.

    Finally we found that the ones column had to equal 19, the tens column had to equal 18 and the hundreds column had to equal 8 you also had to carry numbers.

    So once we worked out that pattern we tried finding out different combinations for the ones column that equalled 19 and found 30. There was a theory that the combinations for the columns went up by 30 each time. 1 column=30, 10 column=60, 100 column equals 90 and all those added together equals 180.

    In this project I got up to finding combinations for the columns.

    In this project I found the start really challenging because we couldn’t think of anything at the start.
