Sorry I changed my answer cause I wasn't so sure if I was right or not.. Here... I'll give you this..
1) A simple sentence is short and to the point, containing just one independent clause. An independent clause can stand alone as a simple sentence while a dependent clause cannot. “I burned dinner” is a good example of a simple sentence/independent clause.
2) A compound sentence is one comprised of two independent clauses joined using a conjunction. Compound sentences can be divided to make two simple sentences by removing the conjunction. “I burned dinner, but I didn’t burn the cake,” is an example of a compound sentence.
3) A complex sentence contains an independent clause and a dependent clause. An example of a complex sentence is this: “I burned dinner but not the cake.”
4) Compound-complex sentences contain two independent clauses and at least one dependent clause. For example: “I burned dinner because I was watching The Walking Dead, but not the cake because I started paying attention to the oven timer when I smelled smoke.”
