Compare -1 and -4.
-1 > -4
-3 + (-5)
-8
5 - 10
-5
-4.1+(-3.8)
-7.9
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

l-6l and -l7l
l-6l > -l7l
1 + (-11)
-10
-9 - 0
-9
3/4 - (-2/4)
5/4
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)

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 describes how to do what operation?
Adding Opposite Integers
4 - (-6)
10
-7/8 - (-9/10) + 1/5
9/40
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
2.0 - 3/7 +(-1/21)
32/21
The shortcut to (-6) - (-16) is keep, change, change
True because...
