+ (addition) - (subtraction) * (multiplication) / (division) % (modulo)
The arithmetic operators follow the standard order of operations.
We can use parentheses to modify that order.
var x = 2; var y = 1.1; console.log(x + y); console.log(x * y); console.log((x+y)*(x-y)); var z = 9; console.log(Math.sqrt(z)); console.log(Math.abs(y/x));
To format a number to a fixed precision:
var x = 3; var y = 1.1; var z = x * y; console.log(z.toFixed(2)); // displays 3.30
