Order of Operations - BIDMAS

Covers the precedence of operations (i.e. BIDMAS), making clear that multiplication/division have the same precedence as each other, as do addition/subtraction. Also contains use of a calculator to input more complicated expressions, with use of the ANS key.

Admiring the works. A little comment: Indices also have a counter balance in roots, just as adding has subtraction and multiplication has division (unless we talk fractional indices). So the operations come nicely in pairs.
