1.
Put in order from least to greatest:
12, 0, -1, -13, 4
Correct Answer
D. -13, -1, 0, 4, 12
Explanation
The given numbers are arranged in ascending order from least to greatest. The correct order is -13, -1, 0, 4, 12.
2.
-4 + (-5) =
Correct Answer
B. -9
Explanation
The given expression is -4 + (-5). When adding two negative numbers, we add their absolute values and keep the negative sign. So, the absolute values of -4 and -5 are 4 and 5 respectively, and their sum is 9. Since both numbers are negative, the sum will be negative as well. Therefore, the correct answer is -9.
3.
-3 + 7
Correct Answer
C. 4
Explanation
The given expression -3 + 7 can be simplified by adding the two numbers together. -3 + 7 equals 4.
4.
-2 - (-4)
Correct Answer
A. 2
Explanation
The given expression is -2 - (-4). To subtract a negative number, we change the subtraction sign to addition and change the sign of the number being subtracted. So, -2 - (-4) becomes -2 + 4. Adding -2 and 4 gives us 2. Therefore, the correct answer is 2.
5.
-9 - 7
Correct Answer
D. -16
Explanation
The correct answer is -16 because when we subtract a negative number from another negative number, it is equivalent to adding the absolute values of the numbers and keeping the negative sign. In this case, we have -9 - 7, which is equal to -16.
6.
Evaluate h - 3 for h = 1
Correct Answer
C. -2
Explanation
To evaluate h - 3 for h = 1, we substitute the value of h into the expression. So, h - 3 becomes 1 - 3, which simplifies to -2. Therefore, the correct answer is -2.
7.
What will be the negative value of – 13?
Correct Answer
D. 13
Explanation
When you negate a negative number, it becomes positive. So, if you have -13 and you want its negative value, it is simply 13.
8.
Write down the predecessor of – 5.
Correct Answer
B. -6
Explanation
The predecessor of -5 is the number that comes before it in the number line. In this case, the number that comes before -5 is -6.
9.
Which of these integers will come between the following pair of integers?
– 8 and – 13
Correct Answer
B. -12, -11, -10, -9
Explanation
The integers that come between -8 and -13 are -12, -11, -10, and -9. Other options contain positive integers which could not exist between -8 and -13.
10.
What will be the sum of this integer equation? (- 8) + (+ 5) + (- 3) + (- 2)
Correct Answer
C. -8
Explanation
The given integer equation is (-8) + (+5) + (-3) + (-2). To find the sum, we add all the numbers together: -8 + 5 + (-3) + (-2) = -8 + 5 - 3 - 2 = -3 - 3 - 2 = -6 - 2 = -8. Therefore, the sum of the integer equation is -8.
