Write a problem multiplying a 3-digit number by a 2-digit number. show all the steps to solve it by using place value and regrouping and by using partial products

So I will use the example of
200
×
20

so what you would do would be so an easier way and fastest way is just put all zeros aside and and when you do you have 2 twos so 2×2=4 so then you get 4 and add all zero u took away which you took 3 zeros so 200×20=4,000
