Hidden Text opens up when a link word is clicked.
Why
This feature can help students pause to think of their own answer before clicking on the link.
Where you may want hidden text
-
Solutions to odd exercises
-
Answers to some examples
-
Proofs for theorems
Add Hidden Text
- Choose EDIT from the top black taskbar.
- Click at the end of this list below the spot to insert your Hidden Text.
- Select ELEMENTS.
- Choose TEMPLATES, then
- drop down to Template: AddHiddenText
- INSERT TEMPLATE.
- Replace Add texts here. Do not delete this text first. with: This is hidden!!
- SAVE !!

spot to insert your Hidden Text
Modify an Example to have a Hidden Solution
- You will hide the Solution to Example 1 below.
- Choose EDIT from the top black taskbar.
- Click ABOVE THE WORD Solution IN EXAMPLE 1 BELOW.
- Select ELEMENTS, Choose TEMPLATES, then drop down to Template: AddHiddenText, INSERT TEMPLATE.
- Copy the text below Solution and paste it on top of Add texts here. Do not delete this text first.
- SAVE!!
- If it looks good, go back to EDIT mode, rename ANSWER to SOLUTION and erase the original Solution so only your hidden Solution remains.
- SAVE !!

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