Hvorfor vises fejlmeddelelser?
Why do error messages appear?
Mest sandsynligt betyder fejlmeddelelsen, at du har indtastet den forkerte ligning. Det betyder, at venstre side ikke er lig med højre side. Den mest almindelige fejl i dette tilfælde er, at i henhold til reglerne for algebra skal multiplikation og division først udføres operationerne og først derefter operationerne med addition og subtraktion.
Most likely the error message means that you entered the wrong equation. This means that the left side is not equal to the right side. The most common mistake in this case is that, according to the rules of algebra, the operations of multiplication and division should be performed first and only then the operations of addition and subtraction.
