Math Operators

Basic math operators

Goal

Get to know JavaScript's basic math operators.

Explanation

  • JavaScript supports standard math operators.
  • + adds numbers.
  • - subtracts numbers.
  • * multiplies numbers.
  • / divides numbers.
  • These operators are used in almost every program.

Analogy

Math operators are like calculator buttons. Each button performs its own math operation.

Code

console.log(5 + 2);
console.log(5 - 2);
console.log(5 * 2);
console.log(10 / 2);

Result: 7 3 10 5

Common mistake

Don't confuse * with the × sign. In JavaScript, multiplication uses *.

Remember

  • ✦ + adds.
  • ✦ - subtracts.
  • ✦ * multiplies.
  • ✦ / divides.
