i) When you added a positive integer, in which direction did you move on the number line ? (Page No. 4)
\nSolution:
\nWhen you add a positive integer you move right side on the number line.<\/p>\n

ii) When you added a negative integer in which direction did you move on the number line ? (Page No. 4)
\nSolution:
\nWhen you add a negative integer you move left side on the number line.<\/p>\n

Question 2.
\nSangeetha said that each time you add two integers, the value of the sum is greater than the numbers. Is Sangeetha right ? Give reasons for your answer. (Page No. 4)
\nSolution:
\nSangeetha is always not correct. When we add – 8 and 3 the sum is (- 8) + 3 = – 5 which is less than 3. Therefore when we add two positive integers then only the sum is greater than the numbers.<\/p>\n

i) When you subtract a positive integer in which direction do you move on the number line ? (Page No. 5)
\nSolution:
\nWhen you subtract a positive integer, you move left side on the number line.<\/p>\n

ii) When you subtract a negative integer, in which direction do you move on the number line ? (Page No. 5)
\nSolution:
\nWhen you subtract a negative integer, you move right side on the number line.<\/p>\n

Question 2.
\nRicha felt that each time you subtract an integer from another integer, the value of the difference is lesser than the two numbers. Is Richa right ? Give reasons for your answer. (Page No. 5)
\nSolution:
\nRicha may not be correct all times. Richa is correct when we subtract a positive integer, but when we subtract a negative integer the difference is greater than the two numbers.<\/p>\n

E.g: 8 – (- 3) = 11 11 > 8 and 11 > – 3
\n5-(-6) = 11 11 > 5 and 11 >-6
\n7-(-8) = 15 15 > 7 and 15 > – 8<\/p>\n
