PEMDAS On Your Calculator

The good news is that your calculator knows PEMDAS. The bad news? Your calculator knows PEMDAS. The problem is that because your calculator knows PEMDAS, you’ll take it for granted that it knows PEMDAS, so you'll let your guard down and get burned by the exceptions I explain in this video. So, look out for the common calculator PEMDAS errors in this video: exponents, fractions, and why you should always use the EE button for Scientific Notation.
