Remember the gumball machine subtraction clip from Sesame Street? I got it from Ssetta which was on #3109 and I remember that very well as a kid. It was also on the old video "Learning To Add & Subtract" and on the CD-ROM Sesame Street Numbers. Here's how it went:
It starts with the gumball machine that had eleven gumballs inside and four of them (the red one, the green one, the pink one, and the blue one) pop out of the machine and leaves seven gumballs. Now we see four gumballs close to the screen, and one of the four gumballs were eaten by some person so it leaves zero gumballs before the zero pops like bubble gum.
Remember that cartoon?
