Line over letters

[smart_10357]

I am working on a math project where I have (line segment) AB = (line segment) CD.  The line segment is shown as a bar over. So do I use the bar over symbol or is there another symbol that I use. I'm using braille group indicators around the letters.

Thanks Susan

Yes indeed, Susan! You are so right; for the line segment notation we use UEB's bar over. Braille on! –Kyle

So, for example, "BC bar" (or "bar over BC") would be transcribed in UEB Math/Science as follows.

;;<,,bc>:

And, "(line segment) AB = (line segment) CD" would be probably be transcribed as follows.

;;;<,,ab>: "7 <,,cd>:;'

P.S. The DBT codes I would use to get that transcription above are ts e bar e bar te (also in the attached screenshot).

Thank you so much!!!

Question: Is it correct to use double capital letter sign in front of AB rather than capital sign A capital B?

 

Also I have a bidirectional arrow over AB. So is it Grade 1, grade 1, open braille group sign capital letter sign capital letter sign AB close braille group sign, bidirectional arrow sign, over sign.

I tried using the braille button and it did not work will send a picture.

First, yes, it is correct to use the two-cell capital letter indicator in front of AB rather than capital A capital B. [Chemistry has different preferences, because its capital letters each mean a totally different element.]

Second, using UEB for it, we would transcribe a bidirectional arrow over AB as follows:

;;<,,ab>.9\wro

You were close. We do need a grade 1 word indicator to start. We do need braille grouping indicators around AB so that the modifier applies to both letters and not just to B. And, your bidirectional arrow is good. \wro

Because UEB does not classify "bidirectional arrow over" with the common modifiers in GTM §12, we should look to GTM §7.9 and use the indicator for "expression directly above." .=.9

Then the arrow does not need any terminator or braille grouping indicators because its start and end are clearly delineated by the arrow indicator and an arrow terminator, respectively. .=| and .=o

Phew.

Braille on!

Thank you.

When do I know to use GTM 7.9  rather than GTM 13. I have a right pointing arrow over BC. Do I use the directly above?

[kdejute]

Thank you for asking. We use GTM 7.9 rather than GTM 12 when §12 does not include the specific modifier we need. A right-pointing arrow is covered in §12, so we should follow the guidelines there.

.=^: simple right-pointing arrow over previous item
