Thursday...

Hi Artix,

Today, I want to tell about my learning. Today in UOI, we got an assessment about the Changing Earth. I got 17 over 19. It is my first medium score that I score in UOI. I am confuse with the difference of plates and crust. Now, I know it because I have research it. A plate is a rock and a crust is the layer of the Earth. In Maths, we have a Top Ten. It is now Tuesday and Thursday. In this top ten, we can use our calculator to solve. If we have a problem like this: 2x9/8+5-5, we can use our calculator. But the method have to be MDAS( Multiplication, Division, Addition and Subtraction) If addition/ subtraction come first and when you solve it in the calculator, it will be big number(sometimes). Then, we check our homework about Perpendicular Lines and Parallel Lines. In this homework, I don't understand why there is an arrow in Parallel Lines. Now I know it. If there are many arrows, it is the sets of parallel lines...


Okay Artix, that's all for today.. Now I want to do my homework... See you on Friday!!!!!
