# Description

Formler og "regnemaskiner", der viser mellemregninger.

Med app´en "Regneregler" får du hjælp til dagligdagens matematik, og du kan genopfriske dine matematikkundskaber med en hurtig oversigt over formler og begreber.

En uundværlig app for elever, forældre, håndværkere og alle andre - uanset niveau - da den både kan bruges som opslagsværk og som hjælp/støtte med forklaringer til selve udregningerne.

App´en tager udgangspunkt i undervisningen i grundskolen, men rummer også mange emner, der bruges på gymnasiale uddannelser eller i erhvervslivet.

Teksterne er skrevet, så de er let forståelige. Vores mål er, at alle skal kunne være med - uanset niveau.

App'en indeholder også en matematisk ordbog over matematiske begreber.

## Fraction calculator

This calculator performs the following operations with fractions : multiplication, division , addition, subtraction , and reduces the fractions and converts the answer as a decimal . They are very easy to use: click on an empty entry field and use the keypad to type in the desired value at the bottom . If you want to enter a negative fraction, click on the small square in front of the input field and shot it appears the sign "-" (if you click this button again the "- " disappears) . Then select the desired operation by pressing the appropriate button on the left of the keyboard ( if you do not select the operation calculator will simply reduce fractions with output greatest common divisor - GCD ) . By clicking on the most right button, your answer becomes a value in the first input field , and you can continue a series of calculations.
