because yes we can. *Because if you want to create a rule. You don't want to write, I used to abbreviate. Example: the blue whale will eat 4 tons of food each day, so if you wanted to know how many tons of food out there for any amount of days that you can write the expression: 4*d where d= number of days. So you can replace the d with any amount of days and you will get the correct answer!* I hoped that helped!
