Why use like <% and <% = in views?

Question

If I write something like:

<% if signed_in?.blank? %> or <%= link_to "Sign Up", sign_up_path %>

What is the difference between the two signs <%and <%=?

Why do it this way instead of just using one for simplicity?

When do I know I need to use <%over <%=?

<%= puts the return value of the code inside the page.

<% just execute the code.
