Products of Integers 11-4
3 ⋅ -2 = -6
Its really repeated addition
or
-2 + -2 + -2 which we learned a few sections ago was equal to -6.
The product of a positive integer and a negative integer is a negative integer.
The product of ZERO and any integer is ALWAYS ZERO!!
a⋅0 = 0
Math imitates life...and Karma(?)
What was the story I told in class... it applies to
Multiplication & Division ...
+ ⋅ + = +
- ⋅ + = -
+ ⋅ - = -
- ⋅ - = +
The product of -1 and any integer equals the opposite of that integer.
(-1)(a) = -a
The product of two negative integers is a positive integer
For a product with NO ZERO factors:
-->if the number of NEGATIVE factors is odd, the product is negative
-->if the number of NEGATIVE factors is even, then the product is positive
Every integer and its opposite have equal squares!!
Remember-- if its all multiplication use the Associative & Commutative Properties of Multiplication to make your work EASIER!!
