The meaning of the numbers affects difficulty in comparing the numbers. The effect is called the meaning effect. This paper demonstrates it in actual science education circumstances. The subjects (Ss) were divided into three groups. Ss in the first group read a writing which is related to evolution. Ss in the second group read the same writing, but each number was replaced with money. Ss in the third group read the same writing, but each number was expressed by Ma (million years). Then, all Ss were asked about the writing. There is no statistical difference among the three groups' percentage of the correctly recalled quantity information. But the meaning of the money makes the percentage of the correctly recalled orders rather high. It was demonstrated by the data that replacing the numbers with money is effective to understand the numbers in evolution.
