Casio FX-115ESPLUS calculator - calculators (Pocket, Battery/Solar, Scientific calculator, Purple, Silver, Plastic)

Product Information

Using a scientific calculator is not an instant process because for a beginner, we have to learn on how the tool operates first that you can check out in their manual since different models vary slightly as well.

For example let’s use the fraction function to solve a problem which is also going to use parenthesis. The first thing we want to mention about the differences between these similar calculators is their menu because if you are familiar with the 115ES Plus, pressing the menu will send you to a list of options while the 991EX has a set of icons to select.The user’s guide clearly explains the multi-line display, how the input and results are displayed, and how to perform the functions of the calculator. What can get confusing is that they are also very similar to each other, making it hard to decide which model we should go after.

In the Statistics Editor, move the cursor to the cell that contains the data you want to change, input the new data, and then press .

Any scientific calculator will be able to work with scientific problems but we prefer those from well-known manufacturers just because they have better build quality and it is easier to find a solution in case we will be facing certain issues with the product later. Either of two special commands ( r∠ θ or a+ b i) can be input at the end of a calculation to specify the display format of the calculation results. When you try with simpler problem such as 2145 then pressing the equal button, they will give you the same format that it simplified but, if you want the more useful form or decimal form depending on what the number will be used for, just press the S-D button and this will transform the result into decimal instantly.

While the Statistics Calculation Screen is on the display, press (STAT/DIST) to display the Statistics Menu. Lastly, I encourage you to ask questions in the comments of the videos or here on this page and I’ll read and respond to them in future videos.

It will weaken your focus on the core exam areas and drain your limited time to complete your FE exam. UPDATE: There are HP calculators available on the internet that have formulas pre-loaded for the FE exam and PE exam. The TI calculator holds your answer and calculation history if you shift between the different modes.
