In the second case, the /key acts like the =key by displaying the result of 750 x 12.
Here’s a longer chain calculation.
456 - 75 ⋅ 68
18.5 1.9
This calculation can be written as: 456 − 75 ⎟ 18.5 x 68 ⎟ 1.9. Watch what happens in the display as you key it in:
Keys: | Display: |
456 | |
18.5 * | |
68 / | |
1.9=
vUsing Parentheses in Calculations
Use parentheses when you want to postpone calculating an intermediate result until you’ve entered more numbers. For example, suppose you want to calculate:
30
85
If you were to key in 30 /85
Keys: | Display: | Description: |
30 /(85- | | No calculation is done. |
12 ) | | Calculates 85 − 12. |
*9 | | Calculates 30 / 73. |
= | | Calculates 0.41x 9. |
