|
|
|
REAL NUMBERS
|
THE SET OF WHOLE NUMBERS AND THEIR OPPOSITES. {..., -3, -2, -1, 0, 1, 2, 3, ...}
|
|
|
NEGATIVE INTEGER
|
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

|
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

|
|
|
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
