Integers
The integer that represents the following statement: "15 yard loss"
-15
Compare -8 and 6
-8 < 6
12 + (-12)
0
5 - 10
-5
Whole numbers and their opposites.
integers
Why is this incorrect? (-2) - (2) = 0
The numbers were subtracted without taking the negative into account. The answer is (-4)
The sum of two negative integers is always positive.
False because...you are to the left of zero and go more negative.
The opposite of 5
-5
Compare -1 and -4.
-1 > -4
-3 + (-5)
-8
-5 - 10
-15
Numbers greater than zero
positive integers
Why is this incorrect? (63) - (-13) = 50
the numbers were subtract as if not (-13). Answer should be 76
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
-14 + (-70)
-84
-29 - 14
-43
The distance a number is from zero.
absolute value
To model -3 + 17, you have 3 red counters and 17 black counters for a total of 20 counters.
Red counters and black counters cancel out, so the three red counters would cancel out three black counters, leaving 14 black counters = 14.
When adding one positive and one negative number, the answer will always be negative.
False, because the sign of the answer will depend on the sign of the number with the greater absolute value.
The integers that come just before and just after -7.
-6 and -8
Order from least to greatest: 0, -2, 4
-2, 0, 4
38 + (-45)
-7
-26 - (-52)
26
The number set of 1, 2, 3, 4, .....
natural numbers
On a number line, do do -18 - 5, you start at -18 and then move right 5 to get -13.
Subtracting a positive means to move left. So from -18, you should move left 5 to get to -23.
Subtracting integers is like adding the opposite signed integer
True
The name of numbers less than zero (using the correct term for the TYPE of numbers they are).
Negative integers
Order for from greatest to least: -7, 0, -3, 2
2, 0, -3, -7
When adding and the signs of integers don't agree, the sign of the answer is determined by ....
The integer with the highest absolute value.
110 - (-370)
480
What does K.I.S.S. stand for?
Keep it, Switch, Switch
Why is this incorrect? The absolute value of 4 is (-4)
Absolute value of 4 is 4 since the 4 is 4 units away from zero. Absolute value is ALWAYS positive.
On a number line, subtracting a negative still means go right.
True because it actually means adding the positive, and adding a positive means go right on a number line.
The only number without a sign.
zero
l-1l, 4, -l-2l, 0, 3, -5 from greatest to least
4, 3, 1, 0, -2, -5
Give an expression to represent the following using only addition, and give the final result: a football team gained five yards on the first play, lost seven yards on the second play, and gained twelve yards on the third play.
5 + (-7) + 12 = 10
-24 - 15 - (-7) - 18
-50
Any number that can be written as a fraction
Rational number
-280 - 100 = -180 because you do 280 minus 100 and keep the negative sign.
When you already start negative, subtraction of a positive means going even lower. So you actually add up 280 and 100 to get 380 and then remember you are still negative, so -380.
The absolute value of a number will always be greater than a negative number.
True because absolute value is always positive, and any positive number is greater than any negative number.
