 friendly letter I'm writhing to you today because its for a assignment for math class and I wanted to let you know what I'm doing in class. What I've been learning in math this module is how to make frequency tables and the order of operations. Frequency tables give you information for bar graphs or line graphs. A table could be about one thing or five different things like colors and coins. With colors it could have lots of different colors or categories in the table. Where in coins every coin is the same. You can also have a sequence in a table by having terms and term number to make an equation like T=N+2. I am also learning about the order of operations. The order of operations is spelled out to help students remember it. Its called PEMDAS! Teachers also sometimes get songs about the subject we are learning. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction which are called the operations. You might ask yourself why the put it in as one word? They do that because of the order they have to go in. Order of Operations! The last thing we have been learning about is bar graphs and line graphs. How are these two graphs different? These graphs are different because a bar graph can have more than one categories when a line graph has one category and is usually about something over a certain period of time.
