The calculator app on your Mac is great when you don’t have to use it too often, but it gets a little tedious to move your mouse to click on each number of an equation. Enter Satechi’s Bluetooh Wireless Smart Keypad. Not only does it work with your Mac, but it also matches Apple’s own Wireless Keyboard so it won’t look like a sore thumb next to your Mac accessories.

The keypad has two functions. It can act like any other calculator by answering all your equations right on its built-in LCD display and can be taken anywhere. It also works as a Bluetooth numberpad and add-on to your existing keyboard, which sends your typed numbers and equations right to your Mac.

You can move it around and place it where it feels most comfortable and it’ll look great next to your Apple Wireless Keyboard and Magic Trackpad or Mouse. It’s great for an office, or just for someone who just likes math.

You can get Satechi’s Bluetooth Wireless Smart Keypad for $50 usually, but it’s being offered for a special price of $34.99.
