Did Bobby err? (Posted on 2022-04-02)

Bobby found the sum of 3 consecutive integers and then the sum of the next 3. Multiplying both results he got 111111111. Is it possible?

Sorry, Bobby.

Of the two numbers being multiplied, one must be even and one must be odd. The product must be even. But Bobby's solution is an odd number.

But of course it is possible Bobby got that answer, but it was by mistake.
