It is interesting that the formula for area of a circle contains an irrational number. Can it’s circumference ever be exact? “Everything in math is a concept” interesting. Can these concepts exist in the minds of other living things? Do ant’s have a concept of 2, or 3, or 100? Just because we give random names to things, does it mean they don’t exist? Hmm, can you see imaginary numbers? Interesting points! I like the way your group builds off each others’ ideas. Hannah, I enjoyed listening to the points you raise, and how we know truths to be true.
