Answer:
10,000
Step-by-step explanation:
100x100=10,000
The two hundreds in this equation have a total of 4 zeros, so you just put those 4 zeros at the end of your answer.
After that, multiply 1 and 1.
That should be 1.
After that, put the 4 zeros behind the 1.
Your answer should be 10,000.
Hope this helps!
