  at this point in my life, as somebody with multiple math degrees, if i ever come across a situation where i need to multiply or divide numbers and one of them is bigger than 12, im going to use a calculator.

    Look at Mr big brain over here who learned his times tables. Sure hope nobody takes his lunch money.

    Shitty Math Pro Tip: If you ever have to work with numbers larger than 10, convert it to scientific notation and then round to a single significant figure.

    ? = 0.04 x 75
    ? = (4 x 10^-2) x (7.5 x 10^1)
    ? ~= (4 x 10^-2) x (8 x 10^1)
    ? = 4 x 8 x 10^-1
    ? = 32 x 10^-1
    ? = 3.2
    ? ~= 3
    

    See how easy that is? Here’s another one:

    ? = 12 x 12
    ? = (1.2 x 10^1) x (1.2 x 10^1)
    ? ~= (1 x 10^1) x (1 x 10^1)
    ? = 1 x 10^2
    ? = 100
    

    Bam, lock it in.

      Depends on the sum though, like if its how many pizzas to buy you should round up.
