Title: Percent Markup and Markdown Obj: I can identify original price as whole and use percent knowledge to solve Mark up and Mark down problems. Demonstrates how to set up and solve 'markup-markdown' word problems. Markdown is so ubiquitous in the Jamstack that many people confuse the M in the JAM acronym to mean Markdown rather than markup. But how did this happen and why does Markdown play such a big role.

Markdown And Markup Language

Markdown Pro is a beautiful and easy to use editor for the popular Markdown markup language, combined with a themed live preview feature, you would never have to write boring documents again.
With Markdown PRO you can write beautiful documentation, notes, essays, term papers all by using plain text to tag your formatting such as bold, italic, lists and others. Need a heading? add # before your text; need to make a text bold? add * around your *text*.
Thanks to the plain text formatting, it will be very easy and fast to type. You will never have to take your hands off the keyboard, so you can focus on writing.
Markdown PRO provides live preview of beautifully formatted text using one of the provided templates. See the results as you type.
It takes less than a minute to learn it!
Your formatting stays where it should, with your text. You can apply a different template at any time to change the colors and size of the text you write.

NOTE: Markdown Pro can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
