Answers
Answer:
1. A number line representing integers is given below
A B C D E F LMNO
-3 and 2 are marked by E and Frespectively. Which integers are marked by B.
D. H. J. M and O?
2. Arrange 7, 5, 4,0 and 4 in ascending order and then mark them on a number line to check your answer.
We have done addition and subtraction of integers in our previous class. Read the
following statements.
On a number line when we
(i) add a positive integer, we move to the right lishe
(ii) add a negative integer, we move to the left.
subtract a positive integer, we move to
(iv) subtract a negative integer, we move to the right.
State whether the following are correct or incorrect. Correct those which
are wrong:
(0) When two positive integer added we get a positive integer.
(ii) When two negative integers are added we get a positive integer. (m) When a positive integer and a negative integer are added, we always get a negative
integer.
(iv) Additive inverse of an integer 8 is (-8) and additive inverse of (-8) is 8.
(v) For subtraction, we add the additive inverse of the integer that is being subtracted. to the other integer
(vi) (-10)+3= 10-3
(vii) 8+(-7)-(-4)=8+7-4
