Success in computation depends partly on the proper
choice of a formula and partly on a neat and methological
arrangement of the work. For the latter computing paper is essential. A convenient size for such a paper is 26” by 16”; this should be devided by faint ruling into 1/4” squares… Every computation should be performed with ink in preference to pencil; this not only ensures a much more lasting record of the work but also prevents eye-strain and fatigue.
