Thus, if we assume that the first column on the right-hand side of the frame to be the unit's place, one hypobead in the first column will be worth one unit; one in the second column will beworth ten unit's, etc. Likewise one altobead in the first column will be five unit's; one in the second column will be | |||||||||||
