  In Duncan's 'Greek Roots Book II Arith' the root arith (numbers) and varied affixes and their definitions are used to teach words dealing with cardinals, ordinals, fractions, size, extent, circles and measurements such as biped, hemisphere, milligram and trigonometry, etc. Mastery of this root and the affixes enables the reader to vastly increase their vocabulary. 8.5" x 11" spiral bound workbook illustrated by artist Holly Bigelow. |
