Connected Sum Problems

GAME INFO
Connected Sum Problems are mathematical puzzles in which you have to drag the numbers so that the two grey circles on the lines of the figures add up to the number in the blue circle. The numbers on the grey discs are part of several sums, so you will have to think carefully about which numbers are part of the sums so that all the operations are correct. When you have succeeded, all the numbers you have used are highlighted in green and you can do another challenge. You can change the shape on the configuration wheel (triangle is the easiest, and pyramid is the most difficult problems), as well as the type of number that is part of the sums: integers, negatives, decimals, as well as their range.
