RATIONAL NUMBER |
Any number that can be written as a fraction.
|
|
|
WHOLE NUMBERS
|
The numbers {0, 1, 2, 3, ...} etc.
There is no fractional or decimal part. And no negatives. |
|
|
INTEGERS
|
THE SET OF WHOLE NUMBERS AND THEIR OPPOSITES. {..., -3, -2, -1, 0, 1, 2, 3, ...}
|
|
|
REAL NUMBERS |
The type of number we normally use, such as 1, 15.82, -0.1, 3/4, etc. Positive or negative, large or small, whole numbers or decimal numbers are all Real Numbers |
|
|
NEGATIVE INTEGER |
Less than zero. A negative number is written with a minus sign in front Example: -5 is negative five. |
|
|
POSITIVE INTEGER |
Greater than zero. (Negative means less than zero. Zero is neither negative nor positive.)Example: 5 is positive five. Sometimes abbreviated "+ve" The values to the right of zero on the number line are all positive: |
|
|
ABSOLUTE VALUE |
How far a number is from zero. Example "6" is 6 away from zero, but "-6" is also 6 away from zero. So the absolute value of 6 is 6, and the absolute value of -6 is also 6. The symbol "|" is placed either side to mean "Absolute Value", so we write: |-6| = 6 |
|
|
SUM |
THE RESULT OR ANSWER TO AN ADDITION PROBLEM DIFFERENCE- THE RESULT OR ANSWER TO A SUBTRACTION PROBLEM |
|
|
PRODUCT |
THE RESULT OR ANSWER TO A MULTIPLICATION PROBLEM |
|
|
QUOTIENT |
THE RESULT OR ANSWER TO A DIVISION PROBLEM |
|
|
PLUS |
A SYMBOL USED FOR POSITIVE INTEGERS |
|
|
MINUS |
A SYMBOL USED FOR NEGATIVE INTEGERS |
|
|
ZERO |
IT HAS NO SIGN. The whole number between -1 and 1, with the symbol 0 Shows that there is no amount |
|
|
EXPRESSIONS |
Numbers, symbols and operators (such as + and ×) grouped together that show the value of something. Example: 2×3 is an expression |
|
|
OPERATIONS |
A mathematical process. The most common are add, subtract, multiply and divide (+, -, ×, ÷). |
|
|
OPERATORS |
An Operator is a symbol (such as +, -, ×, etc) EVALUATE- TO CALCULATE THE VALUE OF. SOLVE |
|
|
EQUATION |
An equation says that two things are equal. It will have an equals sign "=" like this: 7 + 2 = 10 - 1 OR 3X + 5 = 11 |
|
|
VARIABLES |
A symbol for a number we don't know yet. It is usually a letter like x or y. Example: in x + 2 = 6, x is the variable. |
|
|
CONSTANTS |
A fixed value. In Algebra, a constant is a number on its own, Example: in "x + 5 = 9", 5 and 9 are constants |
|
|
EXPONENTS |
The exponent of a number says how many times to use that number in a multiplication. It is written as a small number to the right and above the base number. In this example: 8^2 = 8 × 8 = 64 (The exponent "2" says to use the 8 two times in a multiplication.) |
|
|
ANOTHER NAME FOR EXPONENT IS POWER. BASE |
The number that is going to be raised to a power. Example: in 8^2, 8 is the base |
|
|
VINCULUM |
The horizontal line used to separate the numerator and denominator in a fraction. It can also be any horizontal line placed over an expression to show that everything below the line is one group. |
