 PROBLEM SOLVING: A Student’s Guide

This set of rules will get you through even the longest assignment in the minimum time with little or no thinking. 

Rule 1 

If at all possible, avoid reading the problem.  Reading the problem only consumes time and causes confusion.

Rule 2

Extract the numbers from the problem in the order in which they appear. Pay no attention for numbers written in words.

Rule 3

If rule 2 yields three or more numbers, the best bet for getting the answer is adding them together.

Rule 4

If there are only two numbers which are approximately the same size, then subtraction should give the best results.

Rule 5

If there are only two numbers in the problem and one is much smaller than the other, then divide if it goes evenly-otherwise, multiply.

Rule 6

If the problem seems like it calls for a formula, pick a formula that has enough letters to use all the numbers given in the problem.

Rule 7

Never, never spend too much time solving problems.
