+700 I am really confused, and I really don't know how they work, or how im supposed to solve them.
Is there like a specific theory for it like adding and multiplying or are there multiple ways to solve??
Please help :( thanks. If anyone can explain what these are ill be really happy because i am going to have an exam on this and i really dont understand them at all
