Mnemonic Devices

Mnemonic devices are very helpful. They help us remember certain things when they are tough to remember. One very famous example of a mnemonic device is the order of operations. It can be remembered by the sentence, "Please Excuse My Dear Aunt Sally," or simply the abbreviation, PEMDAS. Taking the first letter of each word can help us remember the order of operations which is, parenthesis, exponents, multiplication, division, addition, and subtraction. Another interesting mnemonic device is the method of loci. This is when you go through a certain area and mentally mark different parts of that area with different labels in order to help you remember what you need to do. For example, a public speaker may mentally note the different corners of a room with different labels in order to help him remember the points that he needs to speak about. Mnemonic devices can be very useful to teenagers like us who need to remember and memorize a great amount of material for tests and classes.
