Deduct and subtract both mean to take an amount away from a total, but the context differs. Deduct is used for official amounts, like taxes, fees or deposits taken from money owed. Subtract is the neutral, everyday word for taking one number away from another.

这两个词都表示“从总数中减去”，但deduct常用于财务、行政场合（如扣税、扣费、扣除押金），强调从应付或应得金额中正式扣除；subtract是中性的数学用语，多用于数字计算，日常语气更强，不带官方扣除的意味。
