The grammatically correct phrasing is: Is my mathematics weak, or am I weak? "Mathematics" is treated as a singular noun in this context. Therefore, the sentence should use "is."
Here's a breakdown:
-
"Mathematics" as a Singular Noun: Although it ends in "s," the word "mathematics" refers to a single field of study or subject. Other examples include physics, economics, and statistics.
-
Correct Verb Usage: Because "mathematics" is singular, it takes a singular verb form. So, we say "mathematics is," not "mathematics are."
-
The Complete Sentence: The original question presents two separate, but related, concepts:
- "Is my mathematics weak?" This focuses on the quality of your understanding and ability in the subject of mathematics.
- "Am I weak?" This focuses on your overall capabilities, perhaps suggesting a lack of confidence or a feeling of inadequacy.
-
Example:
- Incorrect: His mathematics are weak.
- Correct: His mathematics is weak.
- Correct: He is weak in mathematics.
In short, use "is" with mathematics, and consider whether you're assessing your mathematical skills or your broader sense of self.
