Arithmetic Operators Across SQL, MySQL, Python, Java, C, C#, R & JavaScript — Real-World Examples
Arithmetic operators (+, -, *, /, %, exponentiation, and floor division) seem simple, but their behavior differs across languages. Using them without understanding these differences can silently break production systems — especially in finance, analytics, or dashboards. In this guide, we’ll show real, practical examples for each language demonstrating all common operators in action. Before we step into the practical example, let me show you the list of available arithmetic operators across various platforms. Operator and Meaning + →Addition - → Subtraction * →Multiplication / →Division % →Modulus (Remainder) Some languages also include: ** → Exponentiation (Python) ^ → Exponent (R) %% → Modulus (R) // → Floor division (Python) SQL — Payroll Calculations The following SQL query performs arithmetic addition, subtraction, multiplication, division, and modulus on the employees table. Using these arithmetic operators, it calculates the total salary with/without deductions, annual salary, et
