Can you figure out the pattern and solve for the three missing numbers?

All petals and centers each contain a single digit.

There is a unique solution for each missing number.

Hint 1:

The order of the four petals on each flower does not matter. They can be rearranged in any order.

Hint 2:

The center value is calculated using the four petals.


1 Answer 1


I think the answers are

Left petal in top


Centre petal in centre


Right petal in bottom



Multiply the four petals together and take the answer modulo $9$ to give the central square where we take $9$ (mod $9$) instead of $0$ (mod $9$), for this convention.

As pointed out by OP

The central square is also the digital root of the product of the petals.

    $\begingroup$ Great job, that's correct! I based the answers on yesterday's date (June 29). The calculation I used for the central square is digital root which is equivalent to $1+[(x-1)\text{ mod }9]$. $\endgroup$ Commented Jun 30, 2020 at 10:49
