As I said in a recent post, in class we have been learning about variables. Variables are mainly used in geometry to represent an unknown number. The number can be a letter or shape. The letter or shape can represent how much you're saving for a bike or how much money you need to fly to California and back! This helps mathematicians with solving problems and making solutions. This is a graph to show variables and in it, I am using the letter n as my variable. Enjoy!
