Translation:Algebra is different from geometry.
I came across this recently too, Phil. I'm not sure of the actual reason why, but all academic disciplines (physics, geology etc) as well as any classes/lessons/lectures etc associated with them (eg 'my geometry class') get treated like proper nouns and are capitalised.
I agree and we have "different from" as the first choice. But it seems that "than" and "to" are becoming widely used and most dictionaries show these choices.
really? my answer was rejected..
Many thanks for all your work! It's really excellent stuff. And very much appreciated :)
Ι'm unable to understand why it was rejected. I'll report it and hope it's corrected soon. Many thanks for your kind words. Your appreciation is encouraging and we are grateful.
"Different to" is an accepted form and is in the incubator. Please tell us where you found it so we can correct any error.
