I've decided to go back to school after being out for 21 years. I was so nervous because forgot all the math. You have made it so easy and helping me prepare for the HESI test. Thank you because your awesome!

[@MathwithMrJ]

I am 73. I have a BA in psychology and a Master's degree in fine art. But somehow never passed algebra. I am grateful. And have never been in a situation where I needed algebra. It's a beautiful way of making equations. But one that will not be known to me this lifetime.
No regrets.

My eam is tommorow good thing i found this video

[@annapookie2009]

I've decided to improve my maths at the age of 45! I always struggled in school, only got a D in my GCSE after 3 attempts! After struggling to help my kids with their maths during lockdown, I did my functional maths skills course and got 72%. I'm now studying for my GCSE next summer. You're videos have helped me with the topics i've found difficult to wrap my head around. I'm hoping for a grade 6 (B) so need to put in the extra work to go for the higher paper. I hope i'll manage with extra help from Mr J :)

[@anitaohaka2922]

Don't you think your too old

[@annapookie2009]

@anitaohaka2922 wow! You're rude! Too old to improve myself? Too old to improve my knowledge so I can help my kids with their school work?

[@anitaohaka2922]

Sorry 😞

[@anitaohaka2922]

My opinion

[@annapookie2009]

@anitaohaka2922 well my generation were taught to keep our mouths shut if you can't say something nice. A friend of mine, same age has just qualified as a nurse. Bettering yourself in any way should continue throughout your life.

[@jirovaje2789]

i try to answer your problem, and i got it all correct so 4/4 :D

[@lisajones8982]

Iv always had a hard time with math. I've always had a hard time wrapping my brain around(math has rules...lol😂). I've watched several TH-cam videos, and I find so far that Mr. J is most helpful. He explains in detail, which is exactly what I need. I would recommend Mr. J first.

What if the given expression is 3x+2y but the given value is m=3 and n=2? How can I evaluate this?

[@firerblx8062]

It won't be in the book/quiz/ a question ever

[@assumingitsash]

Well, the variables you included are not in your expression. So there is no way to evaluate your expression.

[@nichoalsbeat]

You can't. Nothing has been declared for the variables x and y
