ORDER OF OPERATIONS: 

A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first. (from Purple Math)

digit: symbols used to write numbers (0,1,2,3,4,5,6,7,8,9)

expanded form: shows the value of each digit (plus sign +)

standard form: write numbers by using their digits (number form)

value: how much a digit is worth (ex: 4,598 the 5's value is 500)

 

Can you talk about the difference between the meanings of digit, expanded form, standard form, and value?
