Firstly, allocate fifteen letters from the English alphabet the following values:
E=3, F=9, G=6, H=1, I=–4, L=0, N=5, O=–7, R=–6, S=–1, T=2, U=8, V=–3, W=7, X=11.
You’ll see that O+N+E=1 and T+W+O=2 and so on, but how far is it possible to go before it stops working? This is amazing and a must for your kids to try!!
