Chapter 1 Terms Flashcards
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 cycle1,10,100,1000,10,000 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
