### Two Questions Given to MAT082, MAT102, MAT120 Students

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.

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)

MAT082       6       1
no answer (3); number (1); 0 (1)

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

MAT102      31        0
0 (24); 99 (7)

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).
