If A is a number then -(-A) is =
IMPORTANT: When Subtracting 2 Numbers.
If A, and B are numbers, then a +(-b) =
a - b.
A statement between two quantities usually separated by a sign of inequality.
Signifying less than, greater than, or not equal to.
What does it mean to say the sum of a number and its opposite is 0?
If A Is a number, then
A +(-A) = 0
-A + A = 0
ADDING two integers with DIFFERENT signs
Subtract the smaller absolute value from the Larger absolute value.
Use the Sign of the number w/ the largest Absolute value for the answer.
The Product of an ODD number of _______ is an negative result but, an EVEN number of _________ is a positive number.
Negatives (-) /
A whole number (Positive or Negative)
The additive inverse of a number is the opposite of that number,
the additive inverse of a number x is -x.
The sum of a number and its additive inverse is always zero, that is, x + (-x) = 0.
The magnitude of a number regardless of its sign. Hence, the absolute value of a number “X” is always positive or zero. It is written as |x|.
When the number “X” is represented on a number line, its absolute value is the distance from the origin (zero) to that number.
-l-x l = x
|-x| = x
- |x| = -x
|0| = 0
ADDING Integers with the a SAME signs
Add Their two absolute Values & Use their common sign.
