for the sign + the tiles 3->1->4 are correct because 3+1=4.e.g.
for the sign × the tiles 3->7->2->1 are correct because 3×7=21.e.g.
for the sign - the tiles 1->2->3 are incorrect because 1-2≠3.Hint: leading zeros can be used, so e.g.
with the sign + the tiles 1->7->0->5->2->2 are recognized as 17+5=22.Timed:Play as long as you can, each correct answer grants you score and a (small) time increment.
