10001 × 0 = ____
0
We are multiplying 10001 by 0.
Remember the zero rule of multiplication:
\(a \times 0 = 0\)
This means any number multiplied by zero is zero.
Apply the rule with \(a = 10001\):
\(10001 \times 0 = 0\)
Another way to see it (idea check):
\(10001 \times 0\) means add zero 10001 times:
\(0 + 0 + 0 + \dots + 0 = 0\)
So, the answer is 0.
