How to remove scientific notation in scientific calculator?
The method varies from one model to another. Usually, it is close to those shown below.
TI models: Press [SCI/ENG]. The display shows FLO SCI ENG. Use the left arrow key to select FLO. Then press [=].
On other TI models, press [2nd] [FLO].The display switches to decimal notation.
Casio models: Press [SHIFT][MODE][6:Fix]. You are then prompted to enter a number between 0 and 9. The number you enter fixes the number of decimal digits your results will have. Then press [=].
Sharp models: Press [SET UP] [1:FSE] [0:FIX]. This sets the calculator to use a fixed number of decimal places. Then press [SET UP] [2:TAB]. The display shows TAB(0-9)? Enter the number of digits you want after the decimal point.
You may have to experiment with your specific calculator. When all else fails, READ THE MANUAL.
