As you may know from my past posts, I’m always on the lookout for math apps that are more than just arithmetic. While not a teaching app, I have found another that fits the bill.
Math Formulas is a reference app that contains over 100 formulas covering topics such as Algebra, Geometry, Calculus, Trigonometry, Probability and Statistics, and more. Also, within each category, the formulas are broken down further into sub-categories, such as 2D Shapes and 3D Shapes within Geometry.
Tap on the formula you want and it is shown, along with examples of how it is used. From each formula page, you can navigate up and down to other formulas, or go back in the menu structure. For equations you use often, tap the star on their page, and they will be available in your Favorites list on the main menu.

You probably won’t use all of the included formulas unless you’re in school or do math for a living, but many of them will come in handy. I have often had to look up formulas for area and volume, or combinations and permutations. Or what the letters in the Greek alphabet are, or math prefixes (such as “nano”). This app would have come in handy for those purposes.
Some of the formulas have an explanation of what the variables and placeholders stand for, but not all of them do. If this improvement could be made, it would be more useful than it already is.
Math Formulas is a simple app, but for $1.99 in the iTunes store, it’s handy for reminding you of math formulas on the fly.
