What are the 4 step principle of Polya?
Background Information. Nearly 100 years ago, a man named George Polya designed a four-step method to solve all kinds of problems:
Understand the problem, make a plan, execute the plan, and look back and reflect
. Because the method is simple and generalizes well, it has become a classic method for solving problems.
What is the first step in solving a word problem?

How do I get AUB?
The number of elements in A union B can be calculated by counting the elements in A and B and taking the elements that are common only once. The formula for the number of elements in A union B is
n(A U B) = n(A) + n(B) – n(A ∩ B)
.
What is AUB Venn diagram?
Let A and B be the two sets. … The union of A and B is the set of all those elements which belong either to A or to B or both A and B. Now we will use the notation A U B (which is read as ‘A union B’) to denote the union of set A and set B. Thus,
A U B = {x : x ∈ A or x ∈ B}
.
