equation with words

[Chris Clemens]

I was trying to remember how to correctly show the attached equation. I seemed to remember that there should be no contractions in words used with operation signs. I also though that there can be contractions in words used after an equal sign, but only if in the part of the word not next to the equal sign. Is this correct?

What I did for this equation was to not use contractions in "inches" next to the minus sign, but did use contractions in the word "inches" that ends the equation. Thanks for your help. I'll also try to attach a braille file of what I did.

When attaching a braille file, it is best to save it as a .brf file, so that it can be opened with various braille programs. However, you have explained the situation well enough that with the attached word file I can give you an answer.

Refer to Rule IX, section 55 of the code book, concerning contractions and short-form words. They may not be used in direct contact with an operation sign (the minus in your example), not can they be used before or after the space which immediately preceded or follows a sign of comparions (the equal sign in your example). The lesson manual, Intro to Braille Mathematics, also shows several examples in section 155. -- Additional Rules for Contractions and Short-Form Words.
