Suzzane,
Thanks for the reply. Equation Tools has the ability to change the default font by this address:
"Equation Tools/Tools/Equation Options"
To change the default font you need to have math fonts. I could find some, but I need a font with the same characters that Time New Roman has. Here I send a screen of Equation Options that shows some fonts may be used for Equation.
Moderator Note: Latin Modern Math looks much like Times New Roman. Noto Sans Math apparently is also an available Math font.
