THE ABC'S OF MATH

A = Algebra

• The mathematics of working with variables.
• For Example: If you are going shopping. Three apples costs you $2.75. You need (m) amount of money to get six apples. How much money would it cost?
• The answer is $5.50

B = Brackets
The symbol [ and ]. Brackets are like parenthesis. If you have two or more sets of parenthesis then you use brackets.
For Example:
4 [(X+8) + 9 (X - 1)] = 76 X = 2

C = Converge
To get to a non-infinite limit. For Example: if you have two intersecting lines, the point where they meet is the converging point.

D = Denominator
The bottom part of a fraction. For example, 2 is the denominator for 1/2.

E = exponent

• 2 is the exponent in the number in the backround.
• An exponent is the number that is on top of the big number. It tells you that you have to multiply the big number by itself by the amount of the smaller number.
• For example: If you have 2 over the number 5, than you have to multiply 5 two times. 5 x 5 = 25

F = Fraction
A ratio of numbers or variables. Fractions can't have a denominator of 0. For Example: 3/6 is a fraction but it can be reduced to 1/2.

G = GCF

Example of GCF

H = hexagon

I = inequality

• An equation that uses the greater than or less than signs.
• You can also use than greater than or equal to sign, or the less than or equal to sign.
• For Example: If you have 3 x 10 and 4 x 10 the inequality would be a less than sign because 3 x 10 is smaller than 4 x 10.

J = Joint
The point where two parts of a structure join, but are still able to rotate.

K = Kilometer
A measure of distance that is equal to 1000 meters. My sister ran a 5K run. (which is equal to 3 miles.) Way to go Ella!

L = LCM

Lcm meaning

Examples of LCM

M = Mode
The number that occurs the most often in a list. For Example: 1,1,2,3,4,4,4,5,6 four is the mode because it has appeared the most times on the list.

N = Negative Number
A real number less than 0. I get an allowance every month but since I have to pay so much I am in debt. (i am in negative numbers.)

O = Odds
The chances of something happening. The odds of me getting an iPhone is very unlikely.

P = Probability
A strong chance of something happening. If I flip a coin, the probability of getting a heads is a 50% chance.

Q = Quadrilateral
A polygon with four sides. The sides doesn't need to have equal lengths. For Example: A TV screen is a quadrilateral because it has four sides.

R = ratio

Ratio example

S = sets A group of....

• Numbers
• Variables
• geometric figures
• Or just about anything
• Usually indicated with braces
• For example: {1,2,3} is the set containing the elements 1,2,3

T = Term
Parts of an equation or series separated by + or - signs. For Example: 1 + 2 - 3 = 0. The plus and minus signs are terms.

U = Undecagon
A polygon with 11 sides and angles. An Example of an undecagon is an Australian 50 cent coin.

V = Variable
A letter that can take on different numbers to solve an equation. For Example:
11 + V =13
V = 2

W = Washer Method

X = X-Intercept
A point which a graph intersects the x-axis (must be real numbers).
In the background picture, the red line intersects with the x axis on number five.

Y = y-z plane

Z = zero property
