Thu, 09 Jul 2020 05:21:51 +0000<![CDATA[I have tried to make it work by the use of a button script, but I can’t seem to make it all work. Hope you can help me further... I can import a LaTex string from a list to a row in the CAS-view by writing this in the first row: Element[ List, n ] , where n is the position of the last element in the list and which value is increased by 1 for every click on a button. And I seem to be able to manipulate the expression and get it simplified, although I would prefer to see the expression before and after the simplification. But more importantly, I can’t seem to insert the simplified expression into the same list that the expression came from in the first row. I have tried these methods: List = Insert[ SimplifiedExpression, List, Length( List ) + 1 ] SetValue[ List, Insert[ SimplifiedExpression, List, Length( List ) + 1 ] As the SimplifiedExpression, I have tried to use either $2, LaTex($2) or make a new text object that is defined as LaTex($2). But none of these methods worked. So I hope you have some suggestions for how I can get the simplified expression inserted in the original list. I need this as I would like to get the whole manipulation of the formula viewed in a table with the equation signs aligned under each other and with a explanation of the operation shown next to it.]]>

I have done it by separate the right and the left side of the equation and make a list with equal signs between the two sides of the equation. And use the TableText command as you also suggested.]]>

Wed, 15 Jul 2020 19:52:35 +0000<![CDATA[My next challenge is to use a dropdown-menu for the students to choose which operation they would like to make on both sides of the equal sign. I have managed to get it to work for solving equations. But I can’t seem to find out how I can get it to work with entering a formula in the CAS-view... How can I in a button script combine a IF-sentence with a formula in a row in the CAS-view, so if a student choose “+” in the dropdown-menu, then a written letter (in a input field or dropdown-menu) will be added to both sides of the formula, and if a “*” is chosen in the dropdown-menu, then the written letter will be multiplied on both sides of the formula, an so on. How can I do that ?]]>
