I love this, amazing engineermanship (that's not a word, is it?), guess it's not, it's underlined, lol.....so amazing engineering and creativity to create the concord by radio control.

I had to take a moment and think about the base words in engineer-manship and see how to answer your question if it's a verb, adjective or maybe even a noun?  I think we have a new hybrid word, lol.  "Manship" is a suffix meaning "art or practice competitive nature", yes, I had to look that up and that would mean if an engineer is a noun and then paired with "manship" that would be like saying an engineer is displaying or showing an example of their skills like "workmanship".  Workmanship is a noun, good grief.  I think engineermanship can be used as a noun, verb and adjective depending on the sentence?  Maybe?

Lol....yeah, I kind of went deep in grammar on that one....I was intrigued by your grammar suggestion and worked it out while I was writing. You are a good writer!  Math was not a strong subject of mine, especially after algebra and geometry.  

I never noticed the plural of maths in use but now I'll be paying attention, interesting!  "Road work", versus "road works", also interesting to learn.

On math, what gets me is "imaginary numbers".  My husband is excellent in advanced math so every once in awhile I'll get a little "maths" lesson but I still don't get imaginary numbers.  That still is a "why" for me lol? 

I'm good with all of the basics and accounting.  I posted a Mr. Bean meme on the Konnexu funny thread about accounting yesterday.

All forms of math is fascinating as there's always a right answer.  The problem with grammar is there's always an exception to the rule, however, I have always excelled in grammar.

That's mind boggling!  I think our US debt goes up a trillion every two or three months?  That's insane and truly on the top of my list for national security.
