Computation pad features a five-square-per-inch, cross-section ruling printed on back that faintly shows through to the front. Front is printed with frame margins. Design makes diagramming easier. Three-hole punched pad has holes drilled in the left margin to fit in three-ring binders and is gluebound along that side. The eye-ease green tint paper reduces glare and eyestrain. Letter-size computation pad contains 16 lb. paper and has a 27 point chipboard backer for writing support.
