Calculators aren’t the most exciting apps in the App Store but Tydlig is worth mentioning due to its benefits when teaching mathematics. Notably, you can change any value in a calculation and see the answer updated immediately. This means that you can swap-out numbers quickly without having to re-type the whole thing.
Another unique feature of Tydlig is the ability to link results together. This makes a great teaching aid as it allows students to see how answers are calculated by following the steps and sequences clearly. You can see an explanation, along with other features, in the video at the top of the page.
Tydlig doesn’t just master simple calculations; it’s also pretty nifty at converting figures into graphs. Like before, any number changes are updated in real-time on the graph and the calculations — perfect for trigonometric functions.
