### Expression Word Problem:

A group of students are talking. 2 friends leave. Write an expression for the number of students in the group after the 2 leave...

why?

well the question says "a group of students" it doesn't tell us how many students are in the group. Therefore we use a Variable since the number is unknown.
Also it is -2 because the question states that 2 students Leave the group.

S stands for Students &
G stands for Group.
You could use either one in this question.

6. Great job Selena! You explained it very well. I like how you made the important words bold, but maybe next time you should add color to your post! You should also add a picture or a link to help us understand more! Other than that, you did a good job! Keep it up!
