A

Area

The area of a square or triangle or polygons.

Example: The area of a square with equal 4cm sides is 16cm²

B

• Binomial

• The answer of 2 terms.

• Example: 2x+5²

C

• Coefficient

• It’s the number in an algebra expression

Example: The 8 in 8x

D

• Distributive Property

You multiply the number outside of the brackets (Left side) and you multiply that by what ever is inside the brackets.

Example: 4(2x + 8)

4x2 and 4x8 and go from there

E

• Enlargement

• A number that increases.

• Example: 1=2

F

• Factor

• Factors are numbers before the = sign.

• Example: 5 x 4 = 20

• The 5 and 4 are both factors of 20

G

• Greater Than

• A number that is greater than the other

• Example: 4>1

H

• Hypotenuse

• It is the longest side of a right angle triangle.

• Example: a²+b²=c²

The c² is the longest part/the Hypotenuse.

I

• Involving Brackets

• You first use Distributive Property and after that, that’s when you involve the brackets.

• Example: (after distributive property)

49x-25² = 15² + 7x

J

• Justify

• Justify is to change up how equation looks like.

• Example: (9²)+15

81+15

K

• Kilometer

• A measurement that is mostly used in angle questions.

• Example: John walked to a store 2km away from his home, he then walks another 2km to his friends house. How far is his house now?

L

• Like Terms

• Like terms is a term that has the same variable and power, the coefficient does not need to be the same.

• Example: 4x² and 7x²

M

• Monomial

• An expression in algebra meaning a single term.

• Example: 3x²

N

• Numerator

• The number on the top of the fractions

• Example: 6

----

4

O

• Order of Operation

• Order of operations is when you use BEDMAS to solve a polynomial.

• Example:

12 ÷ 4 + 32 12 ÷ 4 + 93 + 912

P

• Polynomials

• Polynomials are equations that you need to use order of operations to solve.

• Example: 15-4(5+7)/4²

Q

• Quadrants

• The four(quad) squares of a x and y graph

R

Reciprocal

Relating to a number or quantity divided by 1.

S

• Supplementary angles

• Supplementary angles are supplement of 180°

• Example: http://etc.usf.edu/clipart/38500/38579/anglessup1_38579.htm

T

• Trinomial

• Similar to monomial, but 3 terms.

• Example: 3x-4²*6y³

U

• Units

• Units are also known as measurements used in equations for solving.

• Example: mm, cm, km, m, hr, days, years, months, weeks,inches.

V

• Vertically opposite angle

• Also known as the scissor angles, they are equal to each other.

• Example: https://mathsurgery.wikispaces.com/file/detail/vertically+opposite+angles.png/351297366

W

• Whole numbers

• Numbers that are a whole and not a fraction of a hole.

• Example: ½ is half a whole number, (0.5), and numbers like 1,2,3,4,5 are whole numbers.

X

• X axis

• The horizontal line on a graph

• Example: http://www.lukewallin.co.uk/graph/newsuite.htm

Y

• Y axis

• The vertical line on a graph

• Example: http://www.lukewallin.co.uk/graph/newsuite.htm

Z

• Zero pair

• Where you zero out one part of an equation.

• Example: 46=17x• ------ ------• 17 17

• We zero paired the 17.
