Undergraduate and graduate students at Cameron University (N = 158) were given the D'Amore Test of Elementary Arithmetic to test whether or not experience in college mathematics courses might be associated with a relative increase in arithmetic performance compared to those students who had not taken college mathematics courses. We found that only 31.7% of the subjects passed the D'Amore test by achieving 10 out of 10 correct. However, we found that subjects who had taken college math courses had significantly higher D'Amore test Scores than those who had not taken college mathematics courses. Also, higher college mathematics grades were associated with higher D'Amore Test Scores. (Contains 1 table.)
