A former calculus student who is tutoring in a local elementary school stopped by to ask about how and why decimal points work in the lattice algorithm for multi digit multiplication. Here’s the residue of our conversation.
A student submission in response to the question, “Can a hexagon be equiangular, yet have no two sides congruent?” This is presently an A Assignment in my math for elementary teachers course, and is still open (although this diagram purports to resolve it with a counter example).
A College Algebra student wondered whether there could be a function such that its inverse is the same as its opposite. That is, can there be an f such that ?
I had to work graphically to think this through, which you see above.
That task is now an A Assignment.
