Integers
The opposite of 5
-5
Compare -1 and -4.
-1 > -4
-3 + (-5)
-8
5 - 10
-5
Whole numbers
positive integers
An integer and the absolute value of that integer are always opposites.
False because...
6 and the absolute value of 6 are not opposites
Only sometimes true if negative signs are used in the problem
|-42|
42
l-6l and -l7l
l-6l > -l7l
1 + (-11)
-10
-9 - 0
-9
whole numbers, both positive and negative, and zero
integers
Adding or subtracting rational numbers is not done in math
False because...all rational numbers can be converted to fractions and fractions can be added and/or subtracted.
The integers that come just before and just after -7.
-8 and -6
Order from least to greatest: 0, -2, 4
-2, 0, 4
13 + (-6)
7
-6 - (-8)
2
Define absolute value and give me an example of when two numbers can have the same absolute value.
Absolute value is the distance from 0 to that number.
The absolute value of -9 and the absolute value of 9 are both equal to 9.
Subtracting integers is like adding the opposite
True because...
The opposites of whole numbers
Negative integers
Order for from greatest to least: -7, 0, -3, 2
2, 0, -3, -7
Subtracting the digits and keeping the sign of the number that is furthest from zero how to do what operation?
Adding Opposite Integers
4 - (-6)
10
Adding the opposite is a strategy of...?
A strategy to subtracting integers like 7 - 10 is like 7 + (10)
7 + -11 equals a negative number
True because...
-11 has a greater absolute value than 7 so the answer will be negative.
a number line shows a start of 7 and going back 11 spaces will result in -4.
This is neither positive nor negative.
zero
l-1l, 4, -l-2l, 0, 3, -5 from greatest to least
4, 3, 1, 0, -2, -5
The floor of the shallow end to swimming pool is 3 ft below the surface. The deep end's floor is 9 feet deeper. Depth of deep end is....
(-3) + (-9) = -12 feet
Two different values can make this equation true: (x) - (y) = -1
[various answers possible] x is positive and one less than the positive y
Any number that can be written as a fraction is called a ______.
Rational number
The shortcut to (-6) - (-16) is keep, change, change
True because...
