NLN PAX: Mathematics Test: Algebra, Complete Solution

NLN PAX: Mathematics Test: Algebra, Complete Solution Numbers basic building blocks of mathematics. Integers set of whole positive and negative numbers, including zero. These do not include fractions, decimals, or mixed numbers. Prime Number whole number greater than 1 that has only two factors, itself and 1; a number that can be divided evenly by 1 itself. Composite Number whole number greater than 1 that has more than two different factors; any whole number that is not a prime number. Even Number any integer that can be divided by 2 without leaving a remainder. Odd Number any integer that cannot be divided evenly by 2. Decimal Number a number that uses a decimal point to show the part of the number that is less than one. Decimal Point symbol used to separate the ones place from the tenths place in decimals or dollars from cents in currency. Decimal Place position of a number to the right of the decimal point. Decimal or Base 10 System number system that uses ten different digits. Rational Number all integers, decimals, and fractions. Any terminating or repeating decimal number is a rational number. Irrational Number cannot be written as fractions or decimals because the number of decimal places is infinite and there is no recurring pattern of digits within the number. Real Numbers set of all rational and irrational numbers. Mathematical Operations addition, subtraction, multiplication, division Addition increases the value of one quantity by the value of another results in sum Subtraction opposite operation to addition; it decreases the value of one quantity by the value of another quantity results in difference. Multiplication repeated addition; one number tells how many times to add the other number to itself (order doesn't matter). Division
