What I feel like i've mastered this nine weeks is how to find lcm and gcd. i always knew how, but i would get it confused between the two of them. from so much practice, i don't think i will ever forget it now. I struggle with how to find gcd if given the lcm. I don't understand how that's possible. I need to take more legible notes, and maybe I could understand what i was actually writing down.
