How To Show Html As Text

hello, im taking a class in html and i was wondering how i can put html tags in plain text because when i use the html it shows the html code instead of the text.

let me show you an example. lets say i want this text to appear:

<strong>webune</strong>

so when i put this code in my webpage, i see this:

webune

but i wanted to show this on my text:

<strong>webune</strong>
