by combining building blocks! Great! Get a component reward! Try to learn addition! One building block plus one building block is 2 building blocks. 2+2=4 1+2=3 Place the correct number of the building block.
1+1=2 Get the second component reward! Experience the level of subtraction! 2-1=1 3-2=1 4-1=3 5-1=4 6-1=5 Aha! A new component! Addition with carry 1+4+5=10 1+2+3+6=12 12-2=10 2+8=10 3+6+1=10 2+4+2+2=10 Nice job!
