Finding a CG Tool

This is going to sound incredibly silly, so I apologize profusely. I hope this kind of post is allowed here.

I recently downloaded Adobe Photoshop 7.0 onto my computer to create icons, and I can't seem to find the Burn/Dodge tool. It wasn't already in the Toolbox, and I also searched through Load Tools (folders included Art History, Brushes, Crop and Marquee, Text) and there's nothing. It's one of the tools I used a lot when I had Elements, and I'm sure the solution is very easy and I'm just not seeing it.

Thank you in advance :)
