Everyday maths
Splitting a bill, working out a discount, counting days until a festival — computers do this kind of maths instantly. Today you'll learn JavaScript's maths symbols.
The maths symbols
These symbols are called operators — they operate on values.
console.log(8 + 2); // add console.log(8 - 2); // subtract console.log(8 * 2); // multiply console.log(8 / 2); // divide
Numbers can have decimals too. JavaScript uses a dot, not a comma: 2.5
console.log(10 / 4); console.log(0.1 + 0.2);
