What I learned in Math 8
I learned many things in grade 8 math. I all understand it because of our
adviser. I leatned about integers, undefined terms, triangles and triangle
inequalities, angles and parallel lines cut by a transversal ,and probability.
 I learned about integers. I learned how to solve equations with integers. I
learned that when you multiply integers with different signs, the product is
a negative integer. But when you multiply two negative integers, the
product is a postive imteger just like in division. When you subtract two
negative integers, you are going to add it. When you add two different
integers the answer is either positive or negative, but it depends on what
has the the bigger value.
 I learned about undefined terms. I learned the different undefined terms
the point, line and plane. I learned the two two kinds of line the ray and
the line segment. I learned that a point point represents a plane. There
are four types of line: skew lines, parallel lines, perpendicular lines and
intersecting lines. Parallel lines are coplanar lines that do not intersect.
Skew lines are non-coplanar lines that do not intersect. Perpendicular
lines are coplanar lines that intersects to form a right angle. Two points
describe a line. Point can be represented by the tip of your ballpen. Plane
is just like a sheet of paper, a book or the top of the table. The edge of a
table can be described as a line.
 I learned about triangles. Triangles are have three sides. There are 3
types of triangle the right triangle, obtuse triangle, and acute triangle.
There are 3 kinds of triangle the isosceles triangle, equilateral triangle
and scalene triangle. The third side must be equal to the sum of the first
and the second side. The sum of the interior angles of a triangle is 180
degrees. There are postulates in triangle like SSS, SAS and SAA.
 I learned about a parallel cut by a transversal. Parallels are coplanar lines
that do not intersect. When a parallel is cut by a transversal, it will form
angles. Angles like interior angles, exterior angles, alternate-interior
angles, alternate-exterior angles, same-side interior angles, same-side
exterior angles and corresponding angles. A parallel cut by a transversal
has postulates and theorems like EAIT, PSSIAS, AICA, etc.
 I learned about probability. Probability is theathematics of chance. It can
be in a form of ratio, fraction, decimal, etc.. It starts in gaming. Using
talus, a knuckle bone that is used by the ancient people in gambling,
predicting, and many more. It starts because of the curiosity of two
gamblers Blaise Pascal and Pierre de Fermat. Permutation are forms that
something exists can be arranged. Combination is an ordered sequence.
