lys-0071 [83]

Answer:

-24

Step-by-step explanation:

So in short this is what it means:

-4×-2×-3

So to work it out this is what you do:

Deal with the first two numbers; -4 × -2=8

It becomes an eight without a negative because when multiplying numbers with the same signs(positive or negative) the answer is always a positive number thus the answer becomes 8.

Then 8×-3=-24

This is because when multiplying a negative and positive numbers the answer is always a negative numbers thus -24.

So automatically the answer is -24.
