Justin,

Three suggestions are as follows:

A) Try using spreadsheets, likely Excel is available to you on a work computer. Be absolutely sure that the spreadsheet is set up correctly, then just enter new and different data for future calculations and the result should be correct.

How to be sure spreadsheet is set up correctly? Search back into books used for classes, enter examples from the book into a spreadsheet. Highlight cells that are data input. Show intermediate calculation results. Identify the final solution result. Check all of this by hand, pencil, & calculator. Save the spreadsheet for future use, again just changing the input cell values. Have a colleague at work use, check, & verify the spreadsheet.

B) If the calculator you have was more than $20 +/- and is programmable, you likely could create a program on your calculator also, just entering a new & different variable value while running the program on the calculator to get the correct result.

C) Work solutions out by hand, pencil, & calculator, on paper, working slowly & cautiously. Make long calculations by intermediate steps. Think critically about each solution step, does it make sense, check & re-check.

Subject: Avoiding Numerical Mistakes

Hi All,

Maybe this is a simple solution, but ever since beginning my journey at University, I have been affected tremendously by making frequent numerical mistakes in my calculation reports. It gets pretty frustrating because of the need for constant re-work / adjusting values. Though I've tried a lot to eliminate such mistakes, I can't seem to find a solution that works.

Any suggestions?

Kind Regards,
