TwoImportantRules!
• Standalonerule:SecKon2.6• “AleSerorleSers-sequenceisconsideredtobe‘standingalone’ifitisprecededandfollowedbyaspace,ahyphen,oradash.”(Canbeeitheraregulardashorlongdash.)Thisisimportantbecauseithelpsyoudecideif/whenyouneedtousegrade1indicators.
• Grade1Mode:SecKon5.1• “Agrade1indicatorisusedtosetgrade1modewhenthegrade1meaningofasymbolcouldbemisreadasacontracBonmeaningoranumericmeaning.”
• Somesymbolshavea“grade1meaning”andthereforeneedagrade1indicator.
• Note:“Uncontractedbrailleisdifferentfromgrade1mode.”SecBon2.5.2

TheReaderRules!• InUEB,youmustalwaysthinkfromthebraillereader'sviewpoint—whatwillpotenBallybeconfusedormisread?That'swhytheStandingAloneRuleandtheGrade1rulesaresoimportant.• Tocheckyourwork,alwaysask:"Couldthissymbolbeconfusedwithsomethingelse?"• Thatalsomeansthatintechnicalcontexts,theremaybemorethanonewaytodosomething.• Thebasicruleofthumb:Trytominimizeindicatorsinthemiddleofanexpression.

Fractions
• A true fraction has one number written above another number: use the simple numeric fraction line.
• In fractions with numerals, there is no need to repeat the numeric indicator after the fraction line (because it’s allowed in numeric mode along with commas, decimals).
• Mixed fractions are treated as two unspaced numeric items. • Follow print to differentiate between a fraction line or slash.

FractionsinOrdinaryPrint
Used when the print fraction is written with the numerator and denominator written horizontally or linearly instead of vertically. In this case, the slash mark is used:
