Scratchwork is a free online collaborative math whiteboard with various useful features like math recognition, latex expressions, PDF & image annotation, video chat, and more. This math whiteboard provides one of the best ways for math students to practice mathematics on their PC and also for teachers to teach maths with ease. You can practice math problems by simply drawing them on the whiteboard, as you normally do on a notebook. The best part is that it is a collaborative math whiteboard, which means you can invite others  Apart from that, you can also use the math recognition feature to scan hand-written maths with the webcam and then add them to the whiteboard.

Another interesting feature of this online math whiteboard is that it lets you type latex expressions. If you don’t want to type latex expressions, then you can simply draw any expression on the canvas which will be rendered into actual words, numbers, symbols, etc. In addition to that, you can also add text, make video calls, group text conversations, import PDF/images to annotate, highlight terms, and so on. This one is pretty different from the typical online collaborative whiteboard.

After taking the photo, you would need to select the area that contains the math problem or equation. You can do that by dragging the mouse cursor. As soon as you do that, the “Math Recognition” feature will automatically detect the math from the image and insert it into the whiteboard, as shown below. Do note that the free version can recognize basic maths only and not some complex mathematics.
