See what life changes we have planned in the near future!

We find the smallest field containing the number 1 when using the usual addition and multiplication of real numbers.

We show that the integers modulo any prime forms an integral domain under addition and multiplication modulo p.

We show, step-by-step, that the set of all 2 x 2 matrices with real entries forms a ring under addition and multiplication.
