To solve 3 - (-8), we change the subtraction of a negative to addition:
3 - (-8) becomes 3 + 8
Now we add the two numbers together:
3 + 8 = 11
Thus, the correct answer is:
11
6.
What is -3 times -7?
Correct Answer
A. 21
Explanation
To find the product of -3 and -7, we multiply the two numbers together:-3 × -7 = 21Since we are multiplying two negative numbers, the result is positive. Thus, the correct answer is:21
7.
What is the sum of -10 and -5?
Correct Answer
A. -15
Explanation
To find the sum of -10 and -5, we add the two numbers together:-10 + (-5) = -15Both numbers are negative, so we combine their distances from zero. Thus, the correct answer is:-15
8.
What is -30 divided by -10?
Correct Answer
B. 3
Explanation
To find -30 ÷ -10, we determine how many times -10 fits into -30:-30 ÷ -10 = 3Since we are dividing two negative numbers, the result is positive. Thus, the correct answer is:3
9.
What is 4 minus -12?
Correct Answer
A. 16
Explanation

11.
What is the result of 10 + (-3)?
Correct Answer
A. 7
Explanation
To find 10 + (-3), we calculate how to combine a positive number and a negative number. This is the same as subtracting 3 from 10:10 + (-3) = 10 - 3 = 7.On a number line, we start at 10 and move 3 units to the left, landing on 7. Thus, the correct answer is:7
12.
What is the difference of -4 and 6?
Correct Answer
A. -10
Explanation
To determine -4 - 6, we look at moving left on the number line. This means we are taking 6 away from -4:
-4 - 6 = -10.
Starting from -4, we move 6 units left, leading us to -10. Thus, the correct answer is:
-10
13.
How much is -8 + 5?
Correct Answer
A. -3
Explanation
To calculate -8 + 5, we add a positive number to a negative number. This can be visualized as moving to the right on the number line from -8:
-8 + 5 = -3.
We start at -8 and move 5 units to the right, arriving at -3. Thus, the correct answer is:
-3
14.
What is 6 - (-2)?
Correct Answer
B. 8
Explanation
To solve 6 - (-2), we see that subtracting a negative is the same as adding its positive equivalent:
6 - (-2) = 6 + 2 = 8.
This means we add 2 to 6, resulting in 8. Thus, the correct answer is:
8
15.
What is the product of -4 and 6?
Correct Answer
A. -24
Explanation
To find -4 x 6, we apply the rule for multiplying a negative number by a positive number:
-4 x 6 = -24.
We multiply the absolute values, which gives us 24, and since one number is negative, the product is negative. Thus, the correct answer is:
-24
