You can use the following diagram to understand the concept regarding the names of place values (ones, tens, hundreds, thousands, etc.). However, in your case, we will only be working with the ones, tens, hundreds, and thousands.
1. Start by working with the ones. If "one" means "1" and you have 18 of them, then multiply 18 by 1.

18 \times 1 = 18

2. Move onto the tens. If "ten" means "10", and you have 15 of them, then multiply 15 by 10.

15 \times 10 = 150

3. Move onto the thousands. If "thousands" means "1000", and you have 8 of them, then multiply 8 by 1000.

15 \times 100 = 1500

4. Move onto the "thousands" means "1000", and you have 8 of them, then multiply 8 by 1000.

8 \times 1000 = 8000

5. Add the four products together to determine the number.

8000 + 1500 + 150 + 18

= 9500 + 150 + 18

= 9650 + 18

= 9668

Treat each part as a multiplication and then add the answers together, being sure to align all the place holders correctly:
I have calculated them in increasing order of size.

18 ones \to 18 \times 1 = 18

15 tens \to 15 \times 10 = 150

15 hundreds \to 15 \times 100 = 1500

8 thousands \to 8 \times 1000 = 8000

Add theses together being sure to align them correctly

= 9668

I have 18 ones, 15 hundreds, 15 tens, and 8
