Im confused, I dont know how to do this expanded form

(4 times 100,000)+(4 times 10,000)+(9 times 1000)+(2 times 100)+(7 times 1)

Step-by-step explanation:

Well, in expanded notation you would multiply like for example 4 times 100,000 which is 4 hundred thousand or HT which is like it says in the number place chart it would be for every other number like that  I think that's what's it's called and it will be 400,000 and when you add all your expanded notations you would get 449,207 and also 0 doesn't count since it's 0 hope this help :D
