[@annalisa9746]

did better teaching me than my math teacher did, thank you so much

[@Villosa64]

Genius, great lecturing skills. My Algebra honors teacher legits just goes over a random problem while mumbling in 2-3 minutes and expects you to figure out the rest of the worksheet by yourself. The teacher just sits there doing whatever else he wants with the student teaching assistant correcting the paperwork. I don't know why teachers like this are even hired they don't do anything unless you ask them, they just sit there do some slight work and change your grade for money...

[@MariosMathTutoring]

Glad you liked the video and that it helped you.
