• usereferenceswithintheUEBGuidelinesforTechnicalMaterialmanualandotherresourcestoproduceintermediateandadvancedlevelsofSTEMcontent
• describeanduseappropriategradeoneindicatorswithintechnicalandmathemaBcaltranscripBon.

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.
Examples
#a/c #b#a/b #b4e/c4e
Examples
2 1213
#a/c #b#a/b #b4e/c4e
2.53.5
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:
5/6 of the class can go. #e_/#f ( ! class c g4
Model A257/6 has new features. ,model ,a#beg_/#f has new f1tures4
