Explanation
ผลรวม combines ผล (“result”) and รวม (“combine”), giving it the literal sense of “the result of combining.” In mathematics, it means the sum produced by addition. In broader contexts, it refers to the total of expenses, income, scores, quantities, or other numerical values. Common patterns include ผลรวมของ + item (“the total of ...”), หาผลรวม (“find the sum”), and คำนวณผลรวม (“calculate the total”).
Usage
It is commonly used in arithmetic and mathematics, accounting and budgeting, score calculations, spreadsheets, statistics, and reports involving numerical totals.
Caution
ผลรวม refers specifically to a value obtained by adding things together. รวม by itself has broader meanings such as “combine,” “include,” or “gather,” so the two are not always interchangeable. Use ผลคูณ for a product in multiplication and ผลต่าง for a difference in subtraction.
