typos / nitpicks

[j-m-h]

Lesson 6, second to last paragraph: "ELSE run the code indented unter the ..." --> "ELSE run the code indented under the ..."

Lesson 8, explanation of the "countdown" loop should number the steps in the execution (they are referenced by number, but never explicitly numbered)

Lesson 9, first code block under "The ones place": 7%3 is 1, not 4

Lesson 10, should explicitly define what an argument is (even just saying that it is used to mean "input")

Lesson 10, first paragraph under "Parameters and arguments": idk if they'll all know what the sine function is (the power function they'll probably have seen, but they may not know the words "base" and "exponent")

Lesson 10, last paragraph above "Why functions?": It references future chapters (from the book this was taken from), even though we don't use those chapters.
