Q1. Write rules ( Addition/Subtraction of integers  )

(i)    +   +  =  +               (ii)        -    +  =  -   

(iii)  +   -   =  -               (iv)        -   -   =  +

Examples 

i)     +5+3= +8              ii) +10 – 3 = +7                iii) -10 + 30 = +20      iv)   -20-30= -50

( Operation is based on rules and sign of result number is always of greater number )

Q2.Write rules (Multiplication / division of integers)

(i)    +   +  =  +               (ii)        -    +  =  -   

(iii)  +   -   =  -               (iv)        -   -   =  +

(rules are same but result number  sign is based on operation only )

For example

i)     (+5) x (+3) = +15     ii) (+10)  x (- 3) = -30                iii) (-10)  x  (3)  = -30      iv)   (-2)  x (-3) = +6

i)     (+6) / (+3) = +2     ii) (+10)  / (- 5) = -2                iii) (-30)  /  (3)  = -10      iv)   (-12)  / (-3) = +4

Q3.Solve

(i) -3-4  (ii) -3+7  (iii) -8+4 (iv) -7-3  (v) -10-20  (vi) 100-200   ( vii) -8-12    ( viii) -7-17  ( ix) 9+18  (x)  80-20  (xi) -3+2-3   (xii) -5+2-3  ( xiii) -5+3-2-4-3  ( xiv) -10-3-3+4+6-3  ( xv) -15-3-2+4-3+6

Q4.Add

(i) +10 and +15  (ii) -8 and -12  (iii) -5 and 10  (iv) 10 and -20

Q5.Solve

(i) (-7) + (+15)   ( ii) 3 + (-2)   ( iii) -4 – ( -3)   (iv) (-5) + ( -15)   (v) -5 + ( -3) -2

Q6.Subtract

(i) +6 from -13  (ii) -7  from -17   ( iii) -11 from 20   ( iv)  5 from -30   ( v) -8 from -5

Q7.Arrange in ascending order

(i) -1,10,0,-3,5,99,-100    (ii) -99,54,89,70,-3,0   (iii) -20,13,4,0,-5,+5  (iv) +30,-2,0,-6,-20,8
