Hi Mathbug,
Anonymous correctly answered both your questions; this is how you get there:
1000x200
Multiply 1*2 = 2
Then just add in the 3 zeros from 1000 and the two zeros from 200 at the end:
= 200000
For 1000x2000, do the same thing, but since 2000 has three zeros instead of two, it would be
2000000
