Question

The product of each positive integer with -1 is always—
A) Positive
B) Negative
D) 0
D) None of these

Answer 1

Hint: When we multiply any two-positive number, we have always products as a positive integer only. Similarly, whenever we are multiplying any positive and negative integer, we have the product as a negative integer respectively.

Complete step-by-step answer:
We are asked to find the product of each positive integer with -1. An integer is a number that does not include any fraction. It’s the whole number but it includes negative numbers also. So here we have -1 which has a negative sign it means it is usually a negative integer. Hence whenever we multiply any negative integer with any positive integer, we have a negative integer as a product whereas whenever we multiply any positive integer with any other positive integer, we have a positive integer as a product. On the other hand, whenever we multiply any negative integer with any other negative integer, we have a positive integer as a result of the multiplication.
Let’s represent it in a tabular form

integer	integer	Product of both the integer
positive	positive	positive
positive	negative	negative
negative	negative	positive

So here we have -1 which is a negative integer hence while multiplying any positive integer with this negative integer we will always have a negative integer as a product.
So, the product of each positive integer with -1 is always $ negative $ . Hence answer is option ‘B’ from the above options
So, the correct answer is “Option B”.

Note: So whenever we multiply any number with a negative number the product will always be negative so by looking at the option we can directly choose the option having a negative sign and hence we should not multiply those numbers.
