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.
