We are happy to inform that Math Classroom Challenge Version 1.80 is here!
This version includes the new Scenery “Save the seas”, I you can bet is quite different from the others. Here you’ll have to clean the seas and oceans by using “Math Energy”, a special compound that destroys plastics in the sea.
How do you get this Math Energy? We explain it here, with the manual and a videotutorial. Thank you!
