Question 1
(-10) - (+10) + (+10) + (-10) - (-10) =
SOLUTION
Solution :(-10) - (+10) + (+10) + (-10) - (-10) = -10-10+10-10+10 = -20 +10 +0 = -10
Question 2
50 - (- 40) - (- 2) = ?
8
-92
92
-8
SOLUTION
Solution : C
50−(−40)−(−2)=50+40+2 =92
Question 3
Insert one of the following <, >, =, ≤ .
(-3) - (-4) ____ (-4) + (-3)
<
>
=
≤
SOLUTION
Solution : B
(−3)−(−4)=−3+4 =+1(−4)+(−3)=−4−3 =−7
Since +1>−7, (−3)−(−4)>(−4)+(−3)
Question 4
(−8)−7−(+6)−5−(−4)−3−2−(−1)−0= __________
SOLUTION
Solution :(−8)−7−(+6)−5−(−4)−3−2−(−1)−0=−8−7−6−5+4−3−2+1=−26+4−5+1=−26+5−5=−26
Question 5
Find the value of -9-(-10) using the number line:
-1
-2
+1
+2
SOLUTION
Solution : C
-9-(-10) = -9+10
=> Move 10 steps towards right from -9 and you will reach +1.
Question 6
The sum of -50, 45 and -145 will be:
+150
-150
240
140
SOLUTION
Solution : B
-50 + 45 + (-145)
= -50 + 45 - 145
= 45+(-195) = -150
Question 7
Sum of (-12) + (12) + (-6) + (-5) + (-7) + (-10) is _____.
-28
+28
0
-10
SOLUTION
Solution : A
(−12)+(12)+(−6)+(−5)+(−7)+(−10)
=(−12)+(12)+(−28)
=0−28
=−28
Question 8
Which integer is 14 more than -12 ?
-2
+2
26
-26
SOLUTION
Solution : B
-12 + 14 = +2.
So, +2 is 14 more than -12.
.
Question 9
(+12)+(-4) is:
-8
+8
-16
+16
SOLUTION
Solution : B
(+12)+(-4) = 12 - 4 = 8
Question 10
If white buttons represent positive integers and black buttons represent negative integers. Find the net value of all the buttons shown:
+1
-1
0
7
SOLUTION
Solution : B
According to the problem,
There are 4 black buttons = -4
There are 3 white buttons = 3
So, we can write in mathematical form, we get
= (-4) + (+3)
= - 4 + 3
= -1
Thus, the net value of all the buttons is -1.
