A- Algebra
Algebraic Expressions
Algebra uses letters like x
or y or other symbols in
place of unknown values.
–3ax + 11wx2y
An equation is a
mathematical
statement that
two expressions
are equal.
Algebraic Equations
x – 35 = 56k2 + 3
I learned:
WHAT YOU DO TO ONE SIDE, YOU DO TO THE OTHER.
B- BEDMAS
Brackets Exponents
Addition Subtraction
Division Multiplication
BEDMAS is the ORDER OF OPERATIONS
I learned this year In order to solve a question with multiple operations there is
an order to follow
and it is the Order of Operations
First you remove the brackets
Then exponents
Then division and/or multiplication
Then addition and/or subtraction.
C- Coefficient
I learned that A number used to multiply a variable.
Sometimes a letter stands in for the number.
Example:
“6z” means 6 times z and "z" is a variable, so 6 is a coefficient.
D- Denominator
I learned that The bottom number in a
fraction.
Shows how many equal parts the item is
divided into.

I learned:
E-Exponent Laws
Multiplication Law
You add the exponents
23 · 24 = 23+4 = 27
You subtract the exponents
Division Law
25 ÷ 23 = 25-3 = 22
You multiply the exponents
Power Law
(23)2 = 23·2 = 26
F- Fractions
There are 3 way to do fractions
-Adding
-Subtraction
-Multiplication
-Dividing
I learned
To do adding/subtraction fractions
remember to get the
same common denominator, then
add/subtract.
Multiplication is the simplest, all you do is
Multiply the numerator by the numerator,
and the denominator by the denominator.
Dividing may seem complicated at first but all you need to
Do is, Flip the second fraction, and then it turns into a
Multiplication Fraction^^^
G- Geometry
I learned:
Geometry is all about shapes and their properties.
Plane Geometry is about flat
shapes like lines, circles and
triangles. Shapes that can be
drawn on a piece of paper
Solid Geometry is about three
dimensional objects like cubes,
prisms, cylinders and spheres
H- Hypotenuse
I learned:
The hypotenuse is the LONGEST
side of a right triangle.
I- Integers
Integers are like whole numbers, but they also include negative numbers
I learned:
NO FRACTIONS!
You can also add, subtract, multiply, divide integers.
J- Just Do It
Just Do it is used to multiply fractions
All you have to do is JUST DO IT
I learned:
Its simple…….
JUST DO IT
K- Kilometer
I learned:
A Metric measure of distance. Equal to 1,000 meters.
1 kilometer = 0.6 miles approximately.
L- Linear Equations
A linear equation is an equation for a straight line
Example: y = 2x+1 is a linear equation
Examples
y = 3x - 6
y - 2 = 3(x + 1)
y + 2x - 2 = 0
5x = 6
M- Multiplication
I learned:
multiplication is repeated addition.
For example: 7 × 3 = 7 + 7 + 7 = 21
as well as multiplying by whole numbers you
can also multiply by fractions or decimals.
N- Number Line
I learned:
The number line is a line of numbers
that has negative and positive numbers
Greater
Smaller
The lines continue forever left and right
O- Obtuse Angle
An angle that has measure more than 90° and less than 180
I learned:
I learned:
P- π
The ratio of the Circumference to the Diameter of a Circle.
Used to find the area
of a circle, and surface
area of a cylinder
Q- Quadrant
I learned:
Any of the 4 areas made when we divide up a
plane by an x and y axis.
They are numbered I, II, III and IV
R- Rational Numbers
I learned:
A Rational Number is a real number that can
be written as a simple fraction like a ratio
Pi is not a rational
number, it is an
"Irrational Number".
2.12 is a rational number (212/100)
−6.6 is a rational number (−66/10)
S- Surface Area
The total area of the surface of a three-dimensional object.
I learned:
A = 2 (wl+hl+hw)
Formula to get the surface area
of a rectangular prism
A = 2πrh+2πr2
Formula to get the surface area
of a cylinder
T- Triangles
There are 3 types of triangles:
Scalene Triangles
Isosceles Triangles
Equilateral Triangles
I learned:
No equal sides
2 equal sides
3 equal sides
U- Unlike terms
I learned:
Terms with different variables and/or different exponents.
Examples of unlike terms
V- Variable
I learned:
A symbol for a number we don't know yet. It is
usually a letter like x or y.
in y + 20 = 6
y is the variable.
W- Whole number
I learned:
There are no fractions or decimals, not even negatives
X- X axis
I learned:
The line on a graph that goes horizontally
through zero.
Y- Y axis
I learned:
The line on a graph that runs vertically through
zero.
Z- Zero
I learned:
It is the first whole number. It has the property that
every number added to it can equal the number.
