I was watchin your great video on square roots and then my internet went out. I was so mad because I didn't get to finish anything. I had to close up and go to bed. But now I am so behind!!! I really enjoyed the video because it really does refresh my math skills. We all need to brush up on what was taught so long ago. See your videos are good Neuroplasticity Exercises for me! Thank-you so much Bigbear!!!! Have a wonderful Thursday!!!!!
