A magnification of 100% is appropriate and comfortable for the teacher when writing mathematics on OneNote. Once the teacher has completed an example, however, the magnification can be reduced. This allows the students to see the example on one screen and helps them understand the full process. It would be hard for the teacher to actually write the mathematics on OneNote at a reduced magnification. Reducing the magnification afterwards, however, helps the students get the "full picture" and makes the teacher look neat!

When you write mathematics on OneNote you create an object that can be moved around, copied and pasted or resized. Resizing can be useful.

When using the mathematics add-in on OneNote, you will find a range of tools that you can use. In this example, an equation is found that models a skateboard ramp.
