Important Questions Test: Integers - Class 6 MCQ

Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. 

= (-14) + 9 

= -14 + 9 

= -5

-2 is on the right of -3 on the number line as it a bigger number than -3.

Let's evaluate each expression:
a) -48 + 30 = -18 (Negative)
b) -40 + 40 = 0 (Zero)
c) -48 + 79 = 31 (Positive)
d) 48 + (-39) = 9 (Positive)
So, the correct answer is a) -48 + 30, as it results in a negative value.

= (– 4) + (+ 3)

= - 4 + 3 

= - 1

Let's evaluate each inequality:
a) -1 < 0 (True, because -1 is less than 0)
b) 1 < 0 (False, because 1 is not less than 0)
c) -8 > -7 (False, because -8 is not greater than -7)
d) -2 > 4 (False, because -2 is not greater than 4)
So, the correct answer is a) -1 < 0.

The opposite of 50 km of south is 50 km of north.

Every positive integer is larger than every negative integer.

As number over 0^oC are positive numbers, 20^o C above 0^oC will be written as 20. 

Sea level is considered as 0, thus any number below 0 will be a negative number. 

Therfore the appropriate sign for 150 m below the sea level is -150.

Positve numbers are always greater than negative numbers.

Therefore, -13 < 13

1. -12: This is a negative number and is smaller than −1. On a number line, −12 is to the left of −1, so it's less than −1.

2. -3: This is also a negative number and is smaller than −1. On a number line, −3 is to the left of −1, so it's less than −1.

3. 2: This is a positive number. Positive numbers are always greater than negative numbers, so 2 is greater than −1. On a number line, 2 is to the right of −1, which means it is greater.

4. -2: This is a negative number and is smaller than −1. On a number line, −2 is to the left of −1, so it's less than −1.

Conclusion: The only number in the list that is greater than −1 is 2. Positive numbers like 2 are always greater than negative numbers like −1. Therefore, 2 is the correct answer.

0 is greater than every negative number. 

Therefore, 0 > - 15

- Start with the equation: (–11) + (–12)
–11 –12
-we get –23
So, the correct answer is -23.

On the right side of zero lies the positive numbers. 

Therefore, farther a number from zero on the right, larger is its value.
