Onder de grijze vakjes ernaast zit de oplossing.
Veel plezier ermee!
Je kunt de vergelijkingen met oplossingen ook downloaden (zie linkjes onder het instellingen-vak) in twee verschillende bestandsformaten:
- platte tekst (*.txt)
- komma-gescheiden waarden (*.csv)
Daarmee kun je ze gemakkelijk printen, emailen, verwerken in een toets, enzovoorts.
