Build the numbered square used for writing a taweez.
Every row, column and both diagonals add up to your number. The figures around the edge are those totals, so you can check the square before copying it.
The order is not a matter of taste: the sources tie each square to the planet governing the work, and the older books assign Jupiter to provision and learning, Venus to progress and livelihood, Saturn to building and to what is hidden, and Mars to matters requiring force. Copy the figures exactly as they are laid out, and check the totals printed around the edge against your number before you write anything.
