Mathematical Display
Some calculators allow the entering of equations in a way which things like fractions, surds and integrals are displayed in the way they would normally be written.
Casio used to call this Natural Display or Natural textbook display, but now uses Natural-VPAM. SHARP calls this WriteView on its scientific calculators and on its graphing calculators it just uses the term Equation Editor. HP calls this Equation Writer. Mathematica calls this Semantic-Faithful Typesetting. Mathcad calls this standard math notation. Maple has a Math Equation Editor but does not have a special name for this input method. Texas Instruments calls this Math Print.
| Formula | Key strokes | Key stroke count |
|---|---|---|
| 1 + 2 × 3 ↵ Enter | 6 | |
| SIN 3 0 → × COS 3 0 ↵ Enter
SIN ( 3 0 ) × COS ( 3 0 ) ↵ Enter |
9
12 |
|
| 5 - 3 ↵ Enter | 4 | |
| 1 5 + 1 0 + 1 0 + 1 0 ↵ Enter | 12 |
For the second example, two options are given depending on if the calculators will automatically insert needed parentheses or not. Machines equipped with an alphanumeric display will display SIN(30)×COS(30) before pressing ↵ Enter.

Famous quotes containing the words mathematical and/or display:
“What is history? Its beginning is that of the centuries of systematic work devoted to the solution of the enigma of death, so that death itself may eventually be overcome. That is why people write symphonies, and why they discover mathematical infinity and electromagnetic waves.”
—Boris Pasternak (1890–1960)
“In the early forties and fifties almost everybody “had about enough to live on,” and young ladies dressed well on a hundred dollars a year. The daughters of the richest man in Boston were dressed with scrupulous plainness, and the wife and mother owned one brocade, which did service for several years. Display was considered vulgar. Now, alas! only Queen Victoria dares to go shabby.”
—M. E. W. Sherwood (1826–1903)
