Integer Reasoning
Which is greater: -12 or -9? Why
-9(closer to 0)
-18 + 9 = ?
-9
10 - (-7) = ?
17
The temperature is -6 and raises 11 degrees
- 6 + 11 = 5
A diver is at -9 feet and rises 14 feet. Where is the diver now?
-9 + 14 = 5 feet
True or False: -4 + 7 is the same as 7-4
True (both equal 3)
7 + (-12) + 5=?
0
-8 - 6 = ?
-14
You owe $14 and then earn $9
-14 + 9 = -5
You have $20. You spend $35. Then you earn $12
Without solving, decide if the answer will be positive or negative: -15+8
Negative
-6 + (-14) + 9 = ?
-11
-12 - (-5) = ?
-7
A submarine is 32 feet below sea level and rises 18 feet, then drops 7 feet
-32 + 18 - 7 = -21
The temperature is -4. It drops 7 degrees, then rises 15 degrees
-4 - 7 + 15 = 4
Explain why subtracting a negative number increases the value
Subtracting a negative is the same as adding the value
-25 + 17 + (-8) = ?
-16
15 - (-9) - 12 = ?
12
Your bank account starts at $45. You withdraw $68. Then you deposit $23
45 - 68 + 23 = 0
A video game score starts at -50 points. You gain 35 points, lose 20 points, and then gain 10 points
-50 + 35 - 20 + 10 = -25
Write two different expressions that both equal -6
Some answers: -10+4, -3-3, 2-8
Add three integers whose sum is -10
Example: -4 + (-3) + (-3)
Create a subtraction problem where the answer is -3
Example: -1 - 2
The temperature is 3. It drops twice by 8 degrees
3 - 8 - 8 = -13
A hiker starts at sea level, climbs 18 meters, descends 42 meters, then climbs 29 meters. Where is the hiker relative to sea level?
0 + 18 - 42 + 29 = 5
