When we first learn arithmetic, we focus on working with whole numbers. Then, we extend our understanding to fractions and negative numbers In algebra, we transfer these same skills to expressions involving variables. What elementary skills have you used so far in this course, and how have you extended them?​

Well, I don't think I can remember EVERY skill I was taught through the years but in Kindergarten we used Number Sense so we could accurately... also there's estimation and of course PEMDAS. I've also learned how to round up so that the solution is at least around those numbers if the skill is to be applied.

Step-by-step explanation:

I'm not sure if this'll help but go ahead and have it... just try and change it a bit so they don't get ya for plagiarism
