DIRECTED NUMBERS
The numbers which have a direction and a size are called directed numbers.
Multiplication and Division of Integers
MULTIPLICATION
RULE 1: The product of a positive integer and a negative integer is negative.
RULE 2: The product of two positive integers is positive.
RULE 3: The product of two negative integers is positive.
DIVISION
RULE 1: The quotient of a positive integer and a negative integer is negative
RULE 2: The quotient of two positive integers is positive.
RULE 3: The quotient of two negative integers is positive.
SUMMARY OF MULTIPLICATION AND DIVISION RULES
# If the signs are different the answer is negative.
# If the signs are alike the answer is positive
#
example (Multiplication)
Rule 1: 1. (+4) x (-2) = -8
2. (-2) x (+5) = -10
Rule 2: 1. (+6) x (+8) = +48
2. (+6) x (+2) = +12
Rule 3: 1. (-6) x (-8) = +48
2. (-2) x (-4) = +8
example ( Division):
Rule 1: 1. (-8) / (+4) = -2
2. (-12) / (+6) = -2
Rule 2: 1. (+6) / (-3) = -2
2. (+24) / (-6) = -4
Rule 3: 1. (+9) / (+3) = +3
2. (+16) / (+4) = +4
Rule 4: 1. (-6) / (-2) = +3
2. (-42) / (-7) = +6
