A- Algebra Algebraic Expressions –3ax + 11wx 2 y Algebra uses letters like x or y or other symbols in place of unknown values. Algebraic Equations x – 35 = 56k An equation is a mathematical statement that two expressions are equal. WHAT YOU DO TO ONE SIDE, YOU DO TO THE OTHER. I learned:

B- BEDMAS Addition Subtraction Division Multiplication Brackets Exponents 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. 3 7

E-Exponent Laws Multiplication Law Division Law Power Law 2 3 · 2 4 = = 2 7 You add the exponents 2 5 ÷ 2 3 = = 2 2 You subtract the exponents (2 3 ) 2 = 2 3·2 = 2 6 You multiply the exponents I learned:

F- Fractions There are 3 way to do fractions -Adding -Subtraction -Multiplication -Dividing 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^^^ I learned

G- Geometry 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 I learned:

H- Hypotenuse The hypotenuse is the LONGEST side of a right triangle. I learned:

I- Integers Integers are like whole numbers, but they also include negative numbers NO FRACTIONS! You can also add, subtract, multiply, divide integers. I learned:

J- Just Do It Just Do it is used to multiply fractions All you have to do is JUST DO IT Its simple……. JUST DO IT I learned:

K- Kilometer A Metric measure of distance. Equal to 1,000 meters. 1 kilometer = 0.6 miles approximately. I learned:

L- Linear Equations A linear equation is an equation for a straight line Example: y = 2x+1 is a linear equation y = 3x - 6 y - 2 = 3(x + 1) y + 2x - 2 = 0 5x = 6 Examples

M- Multiplication multiplication is repeated addition. For example: 7 × 3 = = 21 as well as multiplying by whole numbers you can also multiply by fractions or decimals. I learned:

N- Number Line The number line is a line of numbers that has negative and positive numbers Greater Smaller The lines continue forever left and right I learned:

O- Obtuse Angle An angle that has measure more than 90° and less than 180 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 I learned:

Q- Quadrant 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 I learned:

R- Rational Numbers 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" is a rational number (212/100) −6.6 is a rational number (−66/10) I learned:

S- Surface Area The total area of the surface of a three-dimensional object. 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 I learned:

T- Triangles There are 3 types of triangles: Scalene Triangles Isosceles Triangles Equilateral Triangles 3 equal sides 2 equal sides No equal sides I learned:

U- Unlike terms Terms with different variables and/or different exponents. Examples of unlike terms I learned:

V- Variable 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. I learned:

W- Whole number There are no fractions or decimals, not even negatives I learned:

X- X axis The line on a graph that goes horizontally through zero. I learned:

Y- Y axis The line on a graph that runs vertically through zero. I learned:

Z- Zero It is the first whole number. It has the property that every number added to it can equal the number. I learned:
