Computation pad features a 5-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 glue-bound along that side. Eye-ease green tint paper reduces glare and eyestrain. Letter-size computation pad contains 200 sheets of 16 lb. paper and has a 27 point chipboard back for writing support.
