Discriminants of equations up to the ninth degree are calculated by using a computer. The numbers of terms included in the discriminants are 2, 5, 16, 59, 246, 1103, 5247, and 26059 for equations of degree two, three, four, five, six, seven, eight, and nine, respectively. Expressions of discriminants up to the fifth degree are included in this paper.
