PEMDAS? or BODMAS? wtf?
We're sitting around this evening, having some quiet family time and the kids started talking maths. Don't ask me why.
Emma said PANDAS, but quickly changed it to PEMDAS. It what she was learning in class (she is in the 5th grade).
Rigo told us that math teacher kept saying "Please Excuse My Dear Aunt Sally" which totally confused him.
PEMDAS? What did it mean?
We grew up with BODMAS.
What are we talking about?? Why, the good old Order of operations
Wikipedia to the rescue :
In the United States, the acronym PEMDAS (for Parentheses, Exponentiation, Multiplication/Division, Addition/Subtraction) is used, sometimes expressed as the mnemonic "Please Excuse My Dear Aunt Sally" or one of many other variations.
In the UK, Australia, New Zealand and South Africa, the acronym BODMAS is commonly used for Brackets, Order, Division, Multiplication, Addition, Subtraction. Since multiplication and division are of the same rank, this is sometimes written as BOMDAS, BIDMAS or BIMDAS where I stands for Indices.
So there you go!
