Math calculators are very helpful for students in solving their math problems. From algebra to geometry, trigonometry to statistics, these calculators are very helpful. Teachers and Parents also get much help from these calculators if they don't find the solution to some difficult math problems.

I wish we could add tags to other people's items without overwriting their authorship!

Steven, you shared a link and I wanted to add a tag to it. However, Diigo does not have a separate "add tag" function. The only way to add a new tag is to share the same link to the group, again. However, it overrides the author - now the link says "Shared by Maria Droujkova" even though you linked it first. I hope it makes sense. We discussed it with Darren when I first started to use Diigo Groups: http://groups.diigo.com/group/math-links/content/can-you-add-tags-to-other-people-s-bookmarks-959243

Hi Maria, thank you for the clarification. I now understand your first comment.

How many times have you prepared an updated or new dynamic math or science PowerPoint or Keynote presentation for class and it would not open in school? Also, how many times has it happened to your students when it's time to give a class presentation? Now you need to postpone their presentation to another day, disrupting even the best planning.

This is my Singapore maths website which caters to the cambridge A level H2 maths syllabus. I have created two problem/worked solution portals-"The Question Locker" and "Beyond H2 Maths" targeted at high school and early college math students, hope they are useful. Peace.
