Polygon
A plane figure bounded by three or more straight-line sides.
Exponent
The exponent of a number shows you how many times the base number is to be used in a multiplication.
23 Three is usually a smaller number (smaller in physical size).
Algebra
A branch of mathematics
in which
letters and other symbols
are used to represent
numbers and quantities in
formulas and equations.
Expanded Form
It shows each digit of a number in its place value
5,372 = 5,000+300+70+2
Factors
Factors are numbers that you multiply together to create a product.
Divisor
The number that divides the dividend.
For example,
when you divide 10 by 2 (10÷2 = 5), 2 is the divisor.
Commutative property
Changing the order of two factors, or addends does not change the product
Addition and Multiplication are commutative,
Division and Subtraction are not.
Base
The base is the number that is multiplied by the exponent.
it is usually a larger number (larger in physical size).
Place Value
The numerical value that a digit has by virtue of its position in a number.
Multiplication property of 1
The product of 1 and any number is that same number.
What Is an Algebraic Expression?
An expression composed of Numbers, Variables, and Operators (+,-,x,÷) no equality or inequality signs
Following is a list of some examples:
2a,
4a+b,
a2,
a-3b.
Division Property of 1
The quotient of any number and 1 is that same number
Subtraction Properties of zero
The difference of any number and that same number is zero
11-11=0
Borowing
To take from (in subtraction) one denomination and add to the next lower.
Quotient
The number resulting from division.
Period
The completion of a number cycle 1,10,100,1000,10,000 etc.
Order of Operations
A rule used to clarify which procedures should be performed first in a given mathematical expression.
(PEMDAS) parentheses exponents (multiplication/division) then (add/subtract)
Addend
One of the numbers that produce a sum.
Product
The result obtained by multiplying two or more Factors (quantities) together.
Distributive property
Multiplication (only multiplication) distributes over addition/ subtraction
2(3+4)= 2x3+2x4
Long Division
Division, usu. by a number of two or more digits, in which each step of the process is written down.
Graphed
The Indication of a number with a dot on the number line.
Commutative Property
The Property that states
Changing the order of two addends/ factors does not change their sum/ multiple
Divedend
The number that is to be divided in a division problem.
For example,
when you divide
10 by 2
(10 ÷ 2 = 5),
10 is the dividend.
Standard Form
Standard form is a way to write numbers using the digits 0-9.
(Another name for scientific notation.)
Evaluate
To ascertain the numerical value of a function.
Diffrence
The result (or answer) of a subtrahend being subtracted from a minuend.
Addition Property of 0
The Property that states
The sum of 0 and any number is that same number.
Addition
Combining two addends to create a sum.
Multiplication sign
x
Digit
A single unit number that uses the symbols 0-9.
Rounding
Replacing a number with an estimate of that number to a given place value.
Subtraction
Finding the diffrence between a subtrahend and a minuend.
Expression
A combination of numbers, symbols, and operations to represent a certain quantity.
For example,
x2 + 2x + 3 is a quadratic expression .
Multiplication
Repeated addition in a different notation
Inequality symbol
A symbol used to indicate a “greater than” or “less than” value. ,
Perimeter
The distance around a Polygon
Subtrahend
A number that is to be subtracted from a minuend
8-3=5
3 is Subtrahend
Sum
The Result (or answer) to two Addends
Exponential Notation
Scientific notation, (standard form/exponential notation) is a way of writing numbers that accommodates values too… 2x2x2= 23
Minuend
A number from which the subtrahend is to be subtracted
8-3=5
8 is Minuend
Division
The operation of finding out how many times the second number will go into the first when dividing one number by a second number.
It is the opposite operation of multiplication,
that is,
a / b = c
is the same as
b × c = a.
Associative Property of Addition
The Property that states
Changing the grouping of addends does not change their sum.
Associative property
Changing the grouping of the factors/addend does not change their product/sum
division and subtraction are not associative
Division Properties of 1
The quotient of any number and that same number is1
Division properties of 0
The quotient of 0 and any number (except 0) is 0
Division Properties of 0
Rule 2
The quotient of any number and 0 is not a number it is what we call UNDEFINED.
Natural Numbers (Counting Numbers)
Any number obtained by adding 1 to it one or more times
A POSITIVE WHOLE NUMBER (as 3, 12, or 432)
Multiplication property of zero
The product of 0 and any number is 0
Evaluating an Expression
Finding the value of an algebraic expression by substituting a value for the variable(s) and then applying the order of operations.
Partial products
The product(s) obtained during the intermediate stages in order to complete a multiplication process.
