​

Answer 1

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
