Hint:
The rule is that any number or anything that we multiply with $0$ the result is $0$ itself. If we notice zero in our multiplication problem statement then our answer should be zero, irrespective of the location of zero.
Complete step by step solution:
Multiplication is nothing but the repeated addition or the multiplication tells us how many times a number should be added. For example if we have $3 \times 4$ then we should understand that we need to add the number $3$ , four times.
Now, when it comes to multiplication with $0$, first we need to understand what multiplication with $0$means. If multiplication means how many times a number should be added, then if we have a problem like $2 \times 0$, then it is telling us that add the number $2$, zero times or no times, if we are adding nothing then the result will be nothing which is zero.
Now, we will solve the given problem by applying above rules,
The given question is $( - 10) \times 0 \times ( - 15)$ is equal to what?
Now, as we know anything multiplied by $0$ give result as zero,
$( - 10) \times 0$ gives $0$, which again multiplied with $ - 15$, we get $0 \times ( - 15) = 0$.
Therefore, the answer is $0$. The correct option is A: $0$.
Note:
By looking at the problem itself we can say the answer if it is multiplied by $0$. But it is not the same case in addition, subtraction or division. If we add or subtract anything by zero then the result will be the number itself. In case of division if a number is divided by zero then the answer will be undefined. If zero is divided by any number then the answer will be zero.
