This is an easy way to solve multiplication with alot of zero's
Add only the numbers, then add the sum of the zeros
So with this problem we do this:-
5*4 is 20, plus the zero in the 50, so the answer is 200
Now we can do the other one:-

5*4 is 20, plus the 4 zeros that we removed is 200,000

Hope I helped. :)
