Product of 3 negative integers

We know that the product of two negative integers is a positive integer. Let us now find out what the product of three negative integers is.

Here is an example:

(-5) x (-2) x (-6)

To find the solution, multiply two integers at a time. So, we have:

(-5) x (-2) = 10

Then multiply the product with the third integer. This gives:

10 x (-6) = -60

Based on this example, we can say that multiplying three negative integers gives a negative product.

Product of 4 negative integers

Let us now see the product of 4 negative integers. Look at this question

(– 4) x (–3) x (–2) x (–1)

As we did in the previous example, we will multiply two integers at a time. So, the above expression can be solved as follows:

(– 4) x (–3) x (–2) x (–1) = 12 x (–2) x (–1)

= (-24) x (-1)

= 24

We first multiplied, -4 and -3, which is 12.

Then we multiplied 12 and -2, which is -24.

And finally, we multiplied -24 and -1. This gave the final answer as 24.
