The CalcuTyper™ may seem like a simple calculator at first, however by holding down a button you can connect it to any device you own. Doing this will sync the two devices. Therefore if you type, for example, 2 + 4 = on your calculator, then the phrase 2 + 4 = 6 will appear on your screen! This is an efficient work around for the lack of mathematical symbols on the keyboard. Using simple Bluetooth technology you can use a CalcuTyper™ as if it were a second keyboard built for math!
