Translation:Esther is teaching mathematics
Could "teaches" as a present tense verb be accepted as well?
"Esther teaches mathematics."
Maths should be accepted as the normal English abbreviation
Yes, "math" as well from the American side.
Are the names of subjects always capitalized?
could this also be Esther is teaching a math lesson?
It is correct and should be accepted but....Duolingo is - Duolingo =D
I agree with the comment below, teaches is also present tense verb
