  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.
