All the numbers have come to a dress-up party in full costume. They all know themselves which costume everyone else is wearing, but you don’t know.
If you pick any two of them and ask them to combine with +, -, × or ÷, they will point out which costume is the correct answer, and they’ll happily do it as often as you want. For example, you might ask for 🐥 + 🦋 and they will point to 🐃. (If the answer isn’t at the party, they’ll tell you that too.)
How do you correctly identify the numbers 0, 1, 2 and 3? How do you do it in as few steps as possible?
Drag numbers to the empty half of the screen to make them stand still. You can use the Name button to label numbers.
Join the party!
