1. flow chart set out

   • terminator=start or the end
   • proces=somthing that happened
   • decition=a question that can be ansewed with yes or no

2. decomposition

   • breaking down a problemdown into smaller and more manageble part
   • we could use this when the problemis to big to solve at once so that we can breack down and solve smaller problems to get the answer to the main question

3. what is a algorithm?

   • an algorithm is a set of step by step intructions for solving a problem.
   • and is a struchered english algorithm used short strutcherea sentances to express the instruction

4. abstraction

   • removing unnecessary details from a problem to creat a simpler problem
   • this is useful because we can identify whaqt parts of the problem are hepful for the solution
   • exsamples of this would be the london unground map,diagrams or moldels
