# 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.

2^{3} 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
