[shannonfaint]

Thanks so much this helped a lot-- during lockdown and quarantine, I didn't learn much since most kids at my old school were underprivileged so they didn't have access to computers, so there was no online school whatsoever. However, I moved away from there (my dad is an Army officer), and my new teacher suggested this video and some from Math Antics to help me out-- thanks again!

[elgordo]

Watching a bunch of your videos before my exam ur a life saver. Great explanations easy to understand. Thank you
