This
really is amazing. Choose any 2-digit number below, add
together both digits, then subtract the total from your original
number -- for instance say you choose 48, you'd add 4+8 = 12, then
subtract 12 from 48 which gives you 36. With this final number,
look it up on the chart and find the relevant symbol. Concentrate
on the symbol and get it clearly in your mind, then click on the crystal
ball and it will show you the symbol you're thinking of!
