Question

: Negative of a negative integer is –
A.Positive
B.Negative
C.Zero
D.None of these

Answer 1

Hint: When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive.

Complete step-by-step answer:
Before attempting the above question, you should have the knowledge of integers and the number line. Also, go through the negative and positive integers and property of integers.
The pack of numbers containing negative, positive, and zero is named as an integer. In this pack, there is not a single number which has a denominator other than one. This pack of numbers can be drawn on the number line. So we can say that the number on the right of the number line is termed as positive and the numbers on the left of a number line are termed as negative, and the number which separates these two types of number is zero which lies in between the positive and negative numbers.
Examples of a positive integer are:
1, 2, 3, 45, 58, …… so on.
Example of negative integer is:
-1, -2, -3, -45, -58, ……. so on.
Negative of a negative integer will obviously be a positive integer. When you multiply a negative by a negative integer, then we will get a positive integer because two negative signs cancel each other.
Let’s take an example as follows:
Assume -10 be a negative integer, then multiply it with the negative sign again.
 $ -\left( -10 \right)=10 $
This shows that the negative of negative is always positive.

Note: Be careful while attempting this question because it may get wrong. Due to the lack of knowledge on integers, especially on a number line, negative and positive integers also. So before attempting this question, please go through the integers.
