A combination problem essentially asks for two answers from different mathematical areas. A simple example could be, "A boy has a bag of marbles. Four marbles are blue. Three marbles are red. Five marbles are white. How many marbles does he have all together? What are the chances of picking a blue marble at random?" The two areas being addressed are simple addition and probability. There are a total of 12 marbles. There is a 1:3 chance of picking a blue marble at random.

What is the difference between solving a problem and analyzing a problem?
When you analyze a problem you look it over which is what analyzing means. You look over the problem and then you solve it. When you solve a problem you solve it and you use certain steps and solve it but of course everyone has there ways to solve a problem but some people have ways to solve it by just analysing it. That is the difference.
What do you need to write in order to calculate things?
You do not need to write anything to calculate things mentally.
An example of a problem that needs to be solved?
write and solve an equation to find the value of x. 8x plus 35 and then 14x-7
What is drqfosac?
DRQFOSAC is a math problem solving strategy. The letters are an anagram for the steps used to solve math problems. D = do (you have decided to do to problem). R = read (read the problem and any graphs/diagrams that go with the problem). Q = question (what question is being asked so you know what unit to use). F = facts (what are the facts given). O = operation (what operation) will you use to solve the problem). S = solve (time to solve the problem). A = answer (write the answer with units). C = check (check your work to make sure there are no silly mistakes). Good luck and happy computing!
