10/7/2018 | We will introduce Gaussian integers in order to decide which integers can be written as a sum of two squares. [Show less] |

10/14/2018 | We will wrap up the discussion of Gaussian integers and prove which integers are the sum of two squares. [Show less] |

10/21/2018 | We introduce the Gini index, an economic metric to measure wealth inequality. [Show less] |

10/28/2018 | We introduce Legendre symbols and quadratic reciprocity to study residues modulo primes. [Show less] |

11/4/2018 | We explore applications of quadratic reciprocity. [Show less] |

11/11/2018 | Instead of our typical definition of addition and multiplication, tropical arithmetic looks at minimum and addition operations. We will graph and find roots of tropical polynomials. [Show less] |

11/18/2018 | We will continue our study of tropical arithmetic by proving a version of the Fundamental Theorem of Algebra for tropical quadratic polynomials. [Show less] |
