how do you/can you add google adsense to a blog page

I would like to add google adsense to my blog pages – while I am not an absolute novice (I have two websites https://www.americanet.com and https://www.mgjsr.com and have weblog running of both sites – I am not php savvy i in fact while I use weblog directly from the webpage – the bulk of my site is built with frontpage – no I don’t use front page while working with the weblog. I have at web development since 1995 but work on the KISS principle thus Front Page is the key to the rest of my websites..
Thank you in advance
