This Mathematical Dictionary is a joint product of students who worked on the international eTwinning project "WIM - World In Math" during the school year 2020/2021. 

It contains a number of mathematical concepts that we used during our work. On each page there is a collection of concepts related to a certain mathematical topic. If you click on the appropriate link, you can read, but also hear how certain terms sound in Croatian, Serbian, Slovenian, Spanish, Greek, Italian, Turkish or Romanian language.
