Answer:
305,018
Explanation:
We have 300,000 for the hundred thousand place.
We have no hundreds. If we have 5 more thousands than hundreds, that technically means that we're adding 5,000 to 0. So we have 5 in the thousands place.
We have 3 more ones than thousands. This means that you have 8 ones.
Lastly, we have four fewer tens than thousands. Since we have 5,000 in the thousands place, we need to do 5 - 4. This equals to one, which means that we have 1 in the tens place.
Let's put it all together.
300,000 + 5,000 + 10 + 8 = 305,018.
