STEP 1 · LEARN

How it works

The * operator converts operands according to numeric rules and produces their product. Storing the expression in a variable makes the result reusable.

Correct example

const total = 6 * 7;
console.log(total);

The 6 * 7 expression is evaluated before 42 is assigned to the constant.

Common mistake

const total = '6 * 7';

Inside quotes this is a string, not an arithmetic expression.

STEP 2 · APPLY

Your exercise

Declare total as the product of 6 and 7, then print total.
