Hidden Text opens up when a link word is clicked.
- Why would we want to use this feature?
-
This feature can help students pause to think of their own answer before clicking on the link.
- Where might you want hidden text?
-
-
Solutions to odd exercises
-
Answers to some examples
-
Proofs for theorems
-
Add Hidden Text
- Click the Edit button on the top black taskbar.
- Click at the end of this list, below Insert your Hidden Text here:
- Select Elements.
- Choose Templates, then select Template: AddHiddenText
- Click Insert template.

Example \(\PageIndex{1}\)
Let \(A = \{\mbox{John}, \mbox{Jim}, \mbox{Dave}\}\) and \(B = \{\mbox{Mary}, \mbox{Lucy}\}\). Determine \(A\times B\) and \(B\times A\).
Solution
We find \[\displaylines{ A\times B = \{ (\mbox{John},\mbox{Mary}), (\mbox{John},\mbox{Lucy}), (\mbox{Jim}, \mbox{Mary}), (\mbox{Jim}, \mbox{Lucy}), (\mbox{Dave},\mbox{Mary}), (\mbox{Dave},\mbox{Lucy})\}, \\ B\times A = \{ (\mbox{Mary},\mbox{John}), (\mbox{Mary},\mbox{Jim}), (\mbox{Mary},\mbox{Dave}), (\mbox{Lucy},\mbox{John}), (\mbox{Lucy},\mbox{Jim}), (\mbox{Lucy},\mbox{Dave})\}.}\nonumber\] In general, \(A\times B \neq B\times A\).
