Joshua from Brooklands Primary, Suffolk says:

I found that $2$ divided $2$ was $1$ (which gave me an odd number).
Hence $2\div2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 15$

Josh from Ampthill, Bedfordshire also got that answer, as well as:

$2 \times2 \times2 \times2 \times2 = 32$, then $32-2 = 30$, then divided by $2$ gives $15$
and
$2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 30$ divided by $2$ to give $15$.

Luke and William from Essex sent very similar solutions to Joshua.
