Help! When I use the Rule #1 Calculators, my numbers come out too large - sometimes in the tens of thousands

Do you happen to be from Germany?

If you are, the issue is with a keyboard incompatibility between German and English.  German keyboards tend to insert commas instead of decimal points. To fix this problem:

• Go into Start (if you are a Windows user)
• Click Systemsteuerung, Regions
• Choose und Sprachoptionen, Regionale Einstellungen:English(USA)

From that point on you should have no problems.

Thank you to Rule #1 fan Michael from Germany for troubleshooting this problem!
