Gas law questions!!?

So I am helping my little cousin with Chemistry and he has NO materials/books/examples. The question asks A mixture of 4 gases exerts a total pressure of 920 torr. Gas A has a partial pressure of 530 torr, gas B has a partial pressure of 75 torr and gas C has a partial pressure of 105 torr. What is the partial pressure of gas D. I know the rule is Ptotal= Pa+ Pb+Pc+Pd... so it should be 920-530-75-105 correct? Should the solution be this simple or am I missing something?
