    • Although I always call it modulus, I like the term integer division better; self-describes the two resultant integers as quotient and remainder.
    • math.isclose() in python defaults to a tolerance of diff <= 1e-09.
    • Cornfield mazes, petting zoos, farms.

    • Spelling bee buddy is great: https://www.nytimes.com/interactive/2023/upshot/spelling-bee-buddy.html
    • The usual typing, ds&a, prep.
    • Choosing k items from n options (and python examples)(repetitions = can choose same option multiple times)
      • No order = combinations.
        • No repetition = n! / (k! * (n – k)!) = math.comb(n, k) = binomial coefficient
        • Repetition = (n+k-1)! / (k! * (n-1)!)
      • Order = permutations.
        • No repetition = n! / (n – k)! = math.perm(n, k)
        • Repetition = n^k
