A new maths app called Photomath lets you use your smart
phone to work out maths problems. All you have to do is point your camera at
the question and it will tell you the right answer. It works by using optical
character recognition technology to read printed equations on a page, then pops
up and augmented-reality display that works through captured equations in real
time.
At the minute it only works on printed text and doesn't pick
up hand written equations but is still quite impressive! Photomath can work out
arithmetic expressions, fractions and decimals, powers and roots, and simple
linear equations.
This is a great tool for parents trying to help with their kids maths homework, or even for students who want to mark their own homework.
