Maths Extension 2

[Domenec Reynolds]

Ineed to install bc (I think this is a language so I am guessing I need to install a parser but I seriously have no clue - would I need to install anything else?) onto Ubuntu 12.04 and any additional maths extension that exists for it. The only place I found to try to download it from was from here which had insufficient instructions for me to be able to actually get this done. Looking around on the site the last update appears to be from the year 2000 which made me very wary of trying to install it and I am not even sure if this the place to get it from or not.

Hello @Mika

Good Afternoon

Sir I want to inform you that i have created and shared few of my extension with the awesome users of kodular. And also helped other learners and extension developers of this community to craete their extensions.

I was going to share these in next week's email but as the closing date for some are very soon and the term is quickly coming to a close I wanted to share them this week! Next week I will share a little more of the research side to enrichment/extension:)

1. Maths Talent Quest, a National competition run by the Mathematical Association of Victoria (in conjunction with the NSW, QLD, WA and SA state based mathematical associations). Several schools I know encourage their extension students from F-6 to enter this competition. It is a fantastic way to encourage students to follow their interests and design and complete a maths investigation (at home or at school). Both individual and group entries are accepted. You can find out more here. Registration opens in April but you can start the projects anytime!

2. Another program that looks amazing for Year 5/6, 7/8 or 9/10 students is the Micro Mathematicians program offered by Melbourne University. The first round applications for this have just closed, but there will be further offering later in the year... so keep an eye out for them! You can read more about this program here. This is open to students across Australia as it is currently being run in a virtual format.

3. Another option are the Australian Maths Trust's Maths Enrichment programs. These are for Year 4-10 students and involve 10-12 week modules that students complete. All the resources including teacher guides, letters to parents etc are included and students are provided with 8 problems to work through over the 12 weeks. This runs from April to October. You can read more here.

4. If you are just looking for tasks to provide enrichment to your students, anything from the www.nrich.maths.org is brilliant. It is in the top 5 websites I recommend to schools for maths planning. You can check out the website here. It has resources from Foundation through to Secondary School.

5. Each year Australian Mathematics Competition is run by the Australian Mathematics Trust. This is open to all students across the world from Years 3-12. When I taught in schools, we offered the opportunity to participate to all our Year 3-6 students. Parents had to indicate if they wanted their child to participate. This year the AMC is taking place from the 4-6th of August and entries close in June. There is both an online and paper option. I think providing opportunities like this is a great way to show student we value their interest in maths just as much as other pursuits, such as sports. I believe participating in the AMC tests provide a challenge for extension students, is a great opportunity for them to shine and provides invaluable test-taking experiences. You can read about the AMC competitions here.

6. The Maths Olympiad has been around for many years and is a great problem solving challenge for extension Year 4-8 Students. Five times throughout the year a group of up to 30 students from your school individually complete a 30minute test sent to you by the competition organisers. You mark the papers and send in the results and prizes are awarded for both individuals and teams.

TexMaths is an addon designed to provide LaTeX support into LibreOffice. LaTeX equations can be inserted as images (SVG or PNG formats) and the LaTeX code is saved into the image attribute for further editing. To insert your first equation into a document, simply type a LaTex math instruction in the text field of the TexMaths Equations window and then click on the LaTeX button. Ex: x(t) = \mu ^2 (t) should produce the equation x(t)=(t)

This release fixes several bugs and add three new features. First, numbered equations now work in multicolumn documents or in multicolumn sections. Note that, due to a bug In LibreOffice, non automatic column widths (i.e. columns with different widths) may lead to incorrect placement of the legend. Second, the TexMaths dialog is automatically resized when it is too small. Third, the preamble now has conditions to deal with latex or xelatex compilers.

New SVG toolbar icons have been designed. In Windows, for LibreOffice version >= 6.2.4, the TexMaths directory is now located at the standard place C:\Users\[username]\AppData\Roaming\LibreOffice\4\user. Therefore, in that case the old hidden directory C:\texmaths-[username] can be safely removed. Also note that LibreOffice 6.2.3 (default version in Ubuntu 19.04) has a bug that breaks TexMaths. So please upgrade to LibreOffice 6.2.4 or above.

1. Why do I need an entire bar for 4 logos (that could be one)?

2. Why doesn't it have a preview? I have to click the button every time I want to edit and see if it looks ok.

3. Autocomplete/Error detection would be great, but of course needs a lot of time

4. Why can't we contribute on e.g. GitHub? It could be a really great and important extension, but like this, it's not really well usable.

This is truly great enhancement to LibreOffice Writer and Impress as it successfully allows to type equations using Latex syntax on both Windows and Linux!

I am using this plugin for more than 5 years and I am really thankful to the author. Mr Roland Thank you very much!!!

I downloaded the latest version of the extension from the SourceForge repository, copied the extension to the folder using the path specified in the error dialog, and ran the extension from the path. I was able to install the extension successfully and get it to work. Changed the rating to 4 stars. However, this bug with using the extension if LibreOffice crashes needs to be fixed.

This is a great extension. I would have given it 5 stars. However, if LibreOffice happens to crash even once, it is next to impossible to re-install the extension. I keep getting the following error:

"C:\Users\USER\AppData\Roaming\LibreOffice\4\user\uno_packages\cache\uno_packages\lu106683zpjl7.tmp_\TexMaths-0.48.2.oxt does not exist."

When I got this error some time back the first time. I simply copied the extension to the folder and ran it from there. It re-installed the extension.

Yesterday, LibreOffice crashed and I cannot get this extension to work. Re-installing LibreOffice and attempting to repair LibreOffice did not solve the problem

What should I do to fix this problem? I need the extension to work properly. Thanks
