GDT asked two questions on the first day of class for the Spring 2007 semester. Students answered the questions anonymously.

1) Everyday we use the base-________ number system.#asked #correct MAT102 31 0 no answer (15); integer (3); dui, dewey, dewy (3); 0 (2); yes (1); 102 (1); 2 (1); 1 (1); factor (1); ball (1); number (1); real (1) #asked #correct MAT082 6 1 no answer (3); number (1); 0 (1) #asked #correct MAT120 27 3 no answer (11); numerical (4); numeric (3); whole (2); roman (1); metric (1); imperial (1); ic (1)2) 99 divided-by 0#asked #correct MAT102 31 0 0 (24); 99 (7) #asked #correct MAT082 6 1 0 (3); 99 (2) MAT120 was given the question: 120 divided-by 0 Total: 27 Correct: 3 0 (15); 120 (6); 1 (2); no answer (1)GDT knew the outcome of the divide-by-0 question, but it was asked so he could immediately get students learning about doing arithmetic with zero.

The base-10 number system question allows a fast forward to integer exponents (zero, one and negatives).
