Answer 2

It appears that there might be a typo or error in the expression you've provided. Let's break it down step by step and correct it if needed:

5 * -6 * +1

First, let's perform the multiplications:

5 * -6 = -30

Now we have:

-30 * +1

Multiplying any number by +1 doesn't change its value, so:

-30 * 1 = -30

So, the correct result of the expression 5 * -6 * +1 is -30, not 0.
