We had a quiz today. Many students did not finish. Please Please Please review over the weekend if you didn't finish. Also I had many students today that said "I did it in my head" Let me see if I can say this clearly, in math you must SHOW YOUR WORK!
So friends please take my advice and show your work. This is the only way I can see where your errors are occuring.
Have a great weekend and I'll see you on Monday
