To perform a calculation, the entire equation is entered then the [ENT] button is selected to evaluate the equation.
For example, 27 + 3 x 8.5 is evaluated as (3 x 8.5) + 27:
| Key | Display | Comments |
|---|
| CLR | | |
| 27 | 27 | |
| + | 27+ | |
| 3 | 27+3 | |
| x | 27+3* | |
| 8.5 | 27+3*8.5 | |
| ENT | 52.5 | Enter evaluates the entire equation at once |
To force the addition to happen before the multiplication, use parentheses. For example, enter (27 + 3) x 8.5:
| Key | Display | Comments |
|---|
| CLR | | |
| ( | ( | |
| 27 | (27 | |
| + | (27+ | |
| 3 | (27+3 | |
| ) | (27+3) | |
| x | (27+3)* | |
| 8.5 | (27+3)*8.5 | |
| ENT | 255 | Enter evaluates the entire equation at once |
This mode follows common order of operation rules for function precedence.
