Thank you.  I passed my Grade 1 test

Doesn’t hurt to come back and say thank you. I passed my cwea1

Man, I've never taken math and been wrecking my brain what to study for the math part that I was overwhelmed with so much info that didn't even have the desire at all to study. Thank God I found his channel. A blessing, for sure. Is this really all the math for grade one?

Taking my 1 tomorrow. These videos have helped me greatly. Thanks for taking the time to do these

12 years later and still watching

You are a good teacher Mr. Davidson thank you. ...

I teach grade 1 math to operators in NC. I recommend your videos to the students. They are very useful.

Thanks for the video. I have an OIT in northern california but have been out of traditional school for about two decades, lol. Have done math refreshers for various job related tests but not a natural math wiz so always great when someone simplifies it like this.

Gonna check out the other videos! Thanks again!!

Great videos thanks for the help, I am a treatment operator in Arizona and all of this is applicable for our exams as well. Keep up the great work

It would be nice if they showed this in school

Thank you so much for these videos! They really help. Quick question. On example 2 you write out the formula as Lbs/day÷MGD×8.34 Lbs/gal. But shouldn't it be Lbs/day÷MGD÷8.34 Lbs/gal?

thank you Christine Williams this is very helpful

Your explanation has helped me tremendously in my new career keep the videos coming sir

Thank you so much for your videos----you sure make it all so simple !!!
