When I want to abbreviate the words "Equations" and "Recommendations" in a text, how can I do this?
Solving the above eqs. / eq's. is not possible unless by computers.
After discussing on the research results, we are going to present our recomms. / recomm's. .
1- Which one is correct? eqs. or eq's. ? recomms. or recomm's.?
2- Is there a kind of freedom to abbreviate any word when it is needed? (For example when constructing a PowerPoint presentation, there may not be enough space to type the whole word in a text box and therefore I prefer to use abbreviations).
