I learned many new mathematics words            

We learned about sequences. A Sequence is a set of things that are in order. And, each number in the sequence is called a term. We have two sequences, Arithmetic sequences and Geo metric sequences.   ・Arithmetic sequences In an Arithmetic Sequence the difference (Which can write “d”) between one term and the next is a constant. EX. 2 4 6 8 10 12…… For this example, we need to…

How to find slope?   We learned about slope. This is really important thing for understand graph.   -Important words- Coordinate …..where the point is.  (a,b) Slope ….It can be find by Rise/Run. Rise ….When we have 2 points, ( X1,Y1) and (X2,Y2), Rise is Y1 – Y2. Run ……When we have 2 points, ( X1,Y1) and (X2,Y2),  Run is X1 – X2. Parallel line …. parallel lines have same…

I made a easy mistake on mid term exam because I didn’t pay attention 😋 Question: Factor the binomial 27x^2-9x We must find Greatest common divisor 27^2 & -9x. Than, put it on the out of the bucket. We must pay attention on x, because 27^2 & -9x can be devided by x.              

I learn how to say side or angle in English like adjacent is a Horizontal, distance, ground and opposite is a high, buildings, tree, and hypotenuse is a ladder,  hill angle of sight.
