Apply the apprpriate mathematical prcess t slve air cnditining and refrigeratin prblems that require the additin, subtractin, multiplicatin, and divisin f fractins, whle numbers, mixed numbers, and decimals. 2. Demnstrate mathematical prcesses t slve air cnditining and refrigeratin prblems fr linear, circular, surface, and vlume measurements. 3. Slve fr and interpret percent and equivalents f decimals and fractins applied t air cnditining and refrigeratin. 4. Interpret the functin f equatins applied t mathematical prblems used in air cnditining and refrigeratin. 5. Analyze, express, and slve air cnditining and refrigeratin prblems with equatins. 6. Slve air cnditining and refrigeratin prblems invlving direct and indirect prprtin. 4. Curse Methds f Evaluatin: Categry 1. Substantial written assignments fr this curse include: If the curse is degree applicable, substantial written assignments in this curse are inapprpriate because: This curse primarily invlves skills, demnstratins r prblem-slving.
