Do you "Do the Math" or "Look it up in a chart or table"?
When you want/need to do something that involves math -
Are you a
Do the Math Person
or a
Look it up in a Chart or Table Person?
I tend to be a "Do the Math Person" - because it is (usually) easier for me. I definitely misplace charts and tables - I also tend to misplace my calculators, too - but I have several of them laying around.
I think being able to do basic arithmetic/math is a handy skill to have for quilt-making.
