Understanding Positive and Negative Numbers
What direction do positive numbers go on a number line?
To the right.
How far is -8 from 0?
8 units.
Name two integers.
Examples: -2 and 5 (any whole numbers including negatives, positives, and zero).
What is +5 + -5?
0
+81 + -42 + -63 + +31
7
Identify a positive number on a number line.
Any number greater than zero (e.g., +1, +2, etc.).
What is the smallest magnitude?
Zero (0), because it has no distance from itself.
Explain an additive inverse.
An additive inverse is a number that, when added to its opposite, equals zero (e.g., +3 and -3).
-6 + 4 + -3
-5
Why is 0 considered neutral?
Because it is neither positive nor negative.
Compare the magnitudes of -4 and +4.
They have the same magnitude of 4.
List three integers between -5 and +5.
Examples: -4, 0, 3 (any integers within the range).
-14 + -6 + +10
-10
How do positive and negative numbers appear on a number line?
Positive numbers are to the right of zero, and negative numbers are to the left of zero.
What is the largest magnitude?
The number farthest from zero, regardless of its sign.
Name an integer that is a negative number.
-1, -2, or -3.
-5 + -10 + -7 + +2
-20
What is the opposite of +3?
-3
What is magnitude?
Magnitude is the distance a number is from zero on a number line.
What integer is zero?
Zero (0).
-12 + -3 + +6 + -7
-16
