...add, subtract, multiply, divide, square root, square function...I got one when they came down to $50. They were an unfair advantage in class. I can only count to 21 on my fingers and toes...I'm mathematically declined !!. In calculus, I could set up most problems but not get the answer because of arithmetic mistakes... so I broke down and got one. I used the money I made from my job at a restaurant during the summer (can't remember which one) PS I tried to delete that huge picture and replace it with another but to no avail.
