I like the standard equation editor in Word.

Is there any way to copy an equation from Word into the forum?

Yes--if you are using Office 365.

1. Enter the equation in Word.

2. Change the equation to LateX using the Conversions area in the Equation Tools--Design tab on the ribbon.

(3. Change the equation display format to Linear.)

4. Copy the LaTeX equation markup from Word into the forum.

Note: Step 3 may not be necessary depending on your equation editor settings.

Example:

I write this equation in Word: 1+1/(2+1/(2+1/(2+⋯)))=√2

I check that it displays nicely.

I convert it to LaTeX.

I copy it to the clipboard.

I paste it here.

It looks like this:

$$1+\frac{1}{2+\frac{1}{2+\frac{1}{2+\ldots}}}=\sqrt2$$
