A - Z Math

Adding Polynomials

Adding Polynomials is simply grouping like terms.

BFSDBFSD is a short form phrase for "Best Friends

Share Desert," but is really stating the order of the steps. It is used when we find the variable

to an equality or inequality.

Combining like terms

Combining like terms is very similar to adding Polynomials. To combine like terms we need to

group similar terms to find out their value.

Denominator

A denominator is the bottom number in a fraction. It shows how many parts makes a

whole.

Equilateral Triangle

An equilateral triangle is a triangle in which all of the sides are the same length. All the angles

of an equilateral triangle are 60°.

Find missing angles on triangles

Every triangles angles will add up to 180° regardless of the triangle type.

Graphing Linear EquationsGraphing linear equations is quite simple if you

know linear equations. To graph them, you take the numbers from the "X" column and place them across the "X" axis, then with the equation column

you line it up with the "Y" axis. You will know if you've done it right when you have a straight line

of dots.

How to divide fractionsDividing fractions is quite easy if you use the

right method. With the method I learned all you do is reciprocate one of the fractions, then

multiply them.

Isosceles TriangleAn isosceles triangle is a triangle where two of

the sides are the same length, and one side is different. In an isosceles triangle two of the angles are always the same, while one is

different.

Just Do It

"Just do it" is a term we use when we want to multiply fractions. It means just multiply the

fraction. There's nothing special to it.

Kilometer

A kilometer is a unit used when measuring length. The term kilo is used because it is

made up of 1000 meters. Kilometer is the unit Canadians use rather than Miles.

Like TermsTerms whose variables (and their exponents

such as the 2 in x2) are the same.Ex. 7x and 2x are like terms because the

variables are both "x". But 7x and 7x2 are NOT like terms

Monomial

A monomial is a Polynomial with just one term.

Numerator

A numerator is the top number in a fraction. It shows how many parts of a whole we have.

Order of Operations

Order of Operations is the order in which we complete a math question. An acronym we use

is 'BEDMAS'

Pythagorean TheoremPythagorean theorem is a theorem we use if

we want to find the length of a side on a right triangle, or if we want to find outfit a triangle is

a right triangle. It works only with right triangles.

Quadrant

A quarter of a circle. It is formed by two radii at a right angle in the centre.

Radius

The radius is within a circle. It is a point from the centre to an outer edge. It could also be

looked at as half of the diameter.

Scalene Triangle

A scalene triangle is a triangle where all of the sides are a different length. All the angles are

different.

TangentA tangent is a line that touches a circle at one

point on the outside but is never crossing over it. A tangent will ALWAYS create a right angle

with the radius at the point of contact. Tangents can also create another triangle.

Unequal

The term unequal refers to two things not being equal.

Volume

Volume is the amount of space a 3-Dimensional object occupies.

Whole Number

A whole number is a number without a fraction or a decimal to it.

X axisAn X axis is a line on a graph that runs

horizontally through 0. It can be used to help you measure.

Y axisA Y axis is a line on a graph that runs vertically through 0. It can be used to help you measure.

Zero PairsZero pairs are pairs of numbers that cancel each other out. It is often used when finding

variables.
