Congratulations to Cornie Peters from West Park School in Altona, MB, Canada. Cornie wins the Casio fx-55 Fraction Mate calculator.
Some mathematicians are topologists.
When you change things under these rules, you can form any new figure you want and the topologist would say that the new one and the original one are the same. To the topologist, K and X are the same thing. To the topologist, Q and P are the same thing. Jefferson ES, Charleston, IL Amin Borji. Universal School, Bridgeview, IL Janet Chen.
