You can apply mathematic operations to numbers using some basic operators like:
- Addition:
c = a + b - Subtraction:
c = a - b - Multiplication:
c = a * b - Division:
c = a / b
You can use parentheses just like in math to separate and group expressions: c = (a / b) + d
{% exercise %}
Create a variable x equal to the sum of a and b divided by c and finally multiplied by d.
{% initial %}
var a = 2034547;
var b = 1.567;
var c = 6758.768;
var d = 45084;
var x = {% solution %} var a = 2034547; var b = 1.567; var c = 6758.768; var d = 45084;
var x = ((a + b) / c) * d; {% validation %} assert(x === (((a + b) / c) * d)); {% endexercise %}
