19 thousands plus seven tens equals?

How should we write 19 thousands with digits? We know that one thousand looks like this, a one followed by three zeros. And we have 19 thousands. This means that we need a 19 followed by three zeros.

Now what about seven tens? We know that one ten is a one followed by a zero. And we have seven of those. Saying seven tens is the same thing as saying 70. From there, we need to add 19000 plus 70. 19000 plus 70 equals 19070.
