In Scratch, for multi-step equations, what happens first and what happens next (precedence) is controlled by how you put the blocks together.
In Javascript, it's controlled by the use of round brackets. For example:
var area = width * height;
var thing = (2 + 3) * 5; // thing will equal 25
var other = 2 + (3 * 5); // other will equal 17
