For this case what you should do is fill in the blank with the following verb:
"Gustar"
The verb must be conjugated correctly.
We observe that we refer to a sentence that is plural.
The sentence is in the plural because it is more than one class of mathematics.
Therefore, the complete sentence in Spanish is:
No me gustan las clases de matemáticas
The translation of the sentence in English is:
I do not like math classes
Answer:
"me gustan"
No me gustan las clases de matemáticas
