"We can use special selectors in <code>Regular Expressions</code> to select a particular type of value.",
"One such selector is the digit selector <code>\\d</code> which is used to retrieve the numbers in a string.",
"It is used like this: <code>/\\d/g</code>.",
"For numbers this is often written as <code>/\\d+/g</code>, where the <code>+</code> following the digit selector allows this regular expression to match one or more numbers.",
"We can use special selectors in <dfn>Regular Expressions</dfn> to select a particular type of value.",
"One such selector is the digit selector <code>\\d</code> which is used to retrieve one digit (e.g. numbers 0 to 9) in a string.",
"In JavaScript, it is used like this: <code>/\\d/g</code>.",
"Appending a plus sign (<code>+</code>) after the selector, e.g. <code>/\\d+/g</code>, allows this regular expression to match one or more digits.",
"The trailing <code>g</code> is short for 'global', which allows this regular expression to find all matches rather than stop at the first match.",
"<h4>Instructions</h4>",
"Use the <code>\\d</code> selector to select the number of numbers in the string, allowing for the possibility of one or more digit."
