- Spelling Corrections:
useable→usable(Correct spelling of the word)expensive_calulation→expensive_calculation(The word "calulation" is incorrectly spelled, and the correct spelling is "calculation" from the verb "to calculate")
- Grammar Improvement:
be at conflict→be in conflict(The preposition "at" is replaced with "in" because the correct expression is "to be in conflict with," which always uses the preposition "in")
