Infix Notation
With this mode the precedence of mathematical operators is taken into account. Most graphing calculators by Casio and Texas Instruments use this method. On its scientific calculators, SHARP calls this method Direct Algebraic Logic (D.A.L.), and Casio calls this method Visually Perfect Algebraic Method (V.P.A.M.).
| Formula | Key strokes | Key stroke count |
|---|---|---|
| 1 + 2 × 3 = | 6 | |
| SIN 3 0 × COS 3 0 = | 8 | |
| 5 - 3 = | 4 | |
| 1 5 + 1 0 + 1 0 + 1 0 = | 12 |
