Overheard at the NCTM Regional Meeting in Baltimore:
In the expression x3, what do you call the 3?
In the expression y2, what do you call the 2?
Speaking of exponents — though apropos of absolutely nothing — here’s an equation that appeared in the 1995 Halloween episode of The Simpsons:
178212 + 184112 = 192212
Without a calculator, can you determine whether it’s true or false?
