As you learned in Lesson Three, when whole numbers are connected by a hyphen, only one number sign is required; when whole numbers are connected by a dash, two number signs are needed. Fractions, on the other hand, are always treated individually. When a fraction or a mixed number is connected to another fraction, mixed number, or whole number, either by a hyphen or a short or long dash, a second number sign is required. No space is left in braille before or after the hyphen or dash. Division between braille lines may be made following the print hyphen or dash only. Examples:

½-¾ | ½ — 1½ | ||

½-1 | 1½ -1- ½ | ||

3½-4½ | 2½—3 | ||

3-6 | 9 - 8½ | ||

0—½ |
