Test: Integers - Class 6 MCQ

The sum of -19 and -21 is calculated as follows:
(−19)+(−21)=−40
So, the correct answer is (a) -40.

• -1 is less than 0 because on the number line, -1 is to the left of 0.
• 1 is greater than 0, so the statement "1 < 0"="" is="" />
• -8 is less than -7, making "-8 > -7" false.
• -2 is less than 4, so "-2 > 4" is also incorrect.

• Therefore, the only true statement is "-1 < />

Let's examine each statement to verify its correctness:

1. Statement: −7+(−6)=−13

   • Solution: Adding two negative numbers, −7+(−6)=−13-7 + (-6) = -13−7+(−6)=−13.
   • Result: This statement is true.

2. Statement: −5+1=4

   • Solution: Adding −5 and 1 gives −4, not 4.
   • Result: This statement is false.

3. Statement: 2+(−1)=1

   • Solution: Adding 2 and −1 gives 1.
   • Result: This statement is true.

4. Statement: 8+(−9)=−1

   • Solution: Adding 888 and −9 gives −1.
   • Result: This statement is true.

Therefore, the false statement is:

2: −5+1=4. The correct result should be −5+1=−4.

= (-8) - 3

= -8 - 3 

= - 11

try to  convert this statment in mathematical equation and you will get your answer

= ( -30) + (-12)

= -30 - 12

= -42 

• Start with -4.
• Add -6: -4 + (-6) = -10.
• Add -8: -10 + (-8) = -18.
• Add 8: -18 + 8 = -10.

The sum of -3 and -2 is calculated as follows:
(−3)+(−2)=−5
So, the correct answer is (c) -3, -2.

Let x be the number that needs to be added to -5 to get 4. The equation is:
(5)+x=14
Solving for 
x=14-5=9
So, the correct answer is (d) 9.

Answer: A
Solution:
To calculate 45−(−15) apply the rule of subtraction:

45−(−15) = 45 + 15 = 60

Correct Answer: (A) 60

Answer: C
Solution:
To calculate (−12)−(−7): 

(−12)−(−7) = (−12)+7 = − 5

Correct Answer: (C) - 5
