First you substitute the values. So 7(3) - 15/(5). 7 x 3 is equal to 21, so the equation is now 21 - 15/(5), and 15/5 is equal to 3. You are now left with 21-  3, which is equal to 18.

18-(-4)-8 is the same as 18+4-8, or 14. You can't write the -8 as addition, but you can write the first part.

Hopefully this helps! Let me know if you have any more questions.
