What costume should my daughter wear to a Maths Day Parade?

MummyEthel: What costume should my daughter wear to a Maths Day Parade?
We’ve been asked to make a costume for our kids for Maths Day. I need suggestions! Was thinking of making a pie- for pi. But that’ll be a bit too hard. Any parents done this theme before? What did you do?

Dress her up as a calculator. Make something with felt “number keys” sewn onto it.
