  2. Team A scored -40,10,0 Total score of Team A = -40+10+0 =-30 Team B scored 10,0,-40 Total score of Team B = 10+0+(-40) = 10 + 0 - 40 = -30 Thus, scores of both teams are same. Yes, we can add integers in any order due to commutative property. Class 7 Maths Exercise 1.2 Questions 1, 2, 3, 4 for moreRead more

    Team A scored -40,10,0
    Total score of Team A = -40+10+0 =-30
    Team B scored 10,0,-40
    Total score of Team B = 10+0+(-40) = 10 + 0 – 40 = -30
    Thus, scores of both teams are same.

  5. (i) a=21,b=18 Given: a=21,b=18 We have a-(-b) = a + b Putting the values in L.H.S. = a-(-b)= 21-(-18) = 21+18 =39 Putting the values in R.H.S. = a + b = 21 + 19 = 39 Since, L.H.S. = R.H.S Hence, verified. (ii) Given: a = 118,b = 125 We have a-(-b)=a+b Putting the values in L.H.S. = a-(-b) = 118 = (-Read more

    (i) a=21,b=18
    Given: a=21,b=18
    We have a-(-b) = a + b
    Putting the values in L.H.S. = a-(-b)= 21-(-18) = 21+18 =39
    Putting the values in R.H.S. = a + b = 21 + 19 = 39
    Since, L.H.S. = R.H.S
    Hence, verified.

    (ii) Given: a = 118,b = 125
    We have a-(-b)=a+b
    Putting the values in L.H.S. = a-(-b) = 118 = (-125) = 118+125 =243
    Putting the values in R.H.S. = a+b = 118 + 125 = 243
    Since, L.H.S. = R.H.S
    Hence, verified.
