A is for Algebra

• What is algebra?

• Algebra is math that uses letters like ‘x‘ and ‘y‘ in place of unknown numbers.

• For example; 6 + 2 – x = 6, ‘x‘ is unknown and is often referred to as the variable.

• We learned about algebra is our unit on polynomials

• A polynomial is an expression that can have variables, constants, and/or exponents

Page 3: ABC Math Book

B is for BEDMAS

• BEDMAS stands for; Brackets Exponents Division Multiply Add Subtract

• This is the order in which we complete equations

• We learned about BEDMAS in our first unit, Rational Numbers

• AKA, BEDMAS is the order of operations

Page 4: ABC Math Book

C is for Coefficient

• A coefficient is a number, or other known factor, that is placed (usually) in

front of another quantity – for example -3x (- being the coefficient)

• A coefficient cam be negative or positive, it can also be 1

• It is outside the base number

• We first learned about coefficients in our unit on exponents

Page 5: ABC Math Book

D is for Distributive Property

• The Distributive Law states that multiplying a number by a group of factors

added together is the same as multiplying them separately

Page 6: ABC Math Book

E is for Exponents

• The exponent of a number tells us how many times to multiply that number

by itself

Page 7: ABC Math Book

F is for Fraction

• A fraction is part of a whole

• The bottom number (denominator) states how many parts the whole is divided into

• The top number (numerator) states how much there is

Page 8: ABC Math Book

G is for Greater Than

• In essence, bigger

• The symbol > means greater than

Page 9: ABC Math Book

H is for Height

• The height is the vertical distance from top to bottom

• We learned about this in symmetry and surface area

Page 10: ABC Math Book

I is for Independent Variable

• An independent variable is an “input” fraction

• It is the variable you have control over

Page 11: ABC Math Book

J is for Just do it

• “Just do it” refers to multiplying fractions. Just do it straight across, not that

complicated.

Page 12: ABC Math Book

K is for ________ Enlargement

• Simply put, to make larger

Page 13: ABC Math Book

L is for Like Terms

• Like terms are terms that have identical variables

Page 14: ABC Math Book

M is for Major Arc

• The major arc is the larger arc that joins two points on the circumference of

a circle

Page 15: ABC Math Book

N is for Negative

• There are negative and positive numbers

• Negative numbers are numbers less than zero

Page 16: ABC Math Book

O is for Oblique Lines

• Oblique lines are slanted, rather than up and down or left and right

Page 17: ABC Math Book

P is for Pythagorean Theorem

• Pythagorean theorem states that in a right triangle;

Page 18: ABC Math Book

Q is for Quadrant (circle)

• A quadrant is a quarter of a circle

Page 19: ABC Math Book

R is for Rational Numbers

• A rational number is any number that can be made by dividing one integer by

another

Page 20: ABC Math Book

S is for Symmetry

• Symmetry is one shape becomes identical to another if you flip or turn it.

Page 21: ABC Math Book

T is for Table of Values

• A table of values is a list of numbers that are used to substitute one variable

Page 22: ABC Math Book

U is for Using the Scale, you can find the Scale

Factor

• If you know the scale, than you can easily find the scale factor and vice versa

Page 23: ABC Math Book

V is for Variable

• A variable is usually a letter that represents an unknown number

Page 24: ABC Math Book

W is for With Reduction, it has to be less than

one but more than zero

• To reduce is to make smaller.

• Things get complicated when you get into negatives

Page 25: ABC Math Book

X is for X-Axis

• The X-Axis is the line on a graph that runs horizontally (left-right) through

zero.

Page 26: ABC Math Book

Y is for Y-Axis

• The Y-Axis is the line on a graph that runs vertically (up-down) through

zero.

Page 27: ABC Math Book

Z is for Zero Pairs

• Zero pairs are when you subtract a number by itself
