The Solving Number Word Problems Series

Word Problems are difficult to many. The Solving Number Word Problems Series is the first series of detailed tutorials on how to solve various number problems. Here are the posts.

(1) How to Solve Number Problems Mentally

This introduction discusses various strategies used to solve easy number word problems. Before you solve a problem using paper and pencil, you should try to solve it first mentally.

(2) How to Solve Number Problems Part 1 

This part solves the same numbers in (1) but using algebra. The objective of this part is to introduce how to set up equations based on “word phrases.”

(3) How to Solve Number Problems Part 2

This part introduces more problems that are slightly more complicated than in (2). It also introduces “number problems in disguise.”

(4) How to Solve Number Problems Part 3

This part of the series focus on how to solve consecutive numbers. Problem of consecutive numbers are very common in math tests.

(5) How to Solve Number Problems Part 4

This post discusses more complicated problems and also introduces how to set up solutions to number problems with fractions.

What’s more to come?

Maybe, I’ll have one more post for this series in the future. But for now, I will focus on the next topic which is about age problems.

How to Solve Number Word Problems Part 4

This is the fourth part and the conclusion to the Number Word Problem Series. In the introduction to this series, we have learned How to Solve Number Problems Mentally. In Part 1 and Part 2, we have discussed the basic number word problems, and in Part 3, we have learned how to solve word problems about consecutive numbers.

In this post, we discuss about more complicated problems especially problems that involve fractions. We have already discussed 9 problems in the previous parts of this series, so, we now solve the 10th problem.

Problem 10

There are 5 consecutive numbers. The sum of the second and the fourth number is 82. What is the largest number? Continue Reading

How to Solve Number Word Problems Part 2

This is the second part of the the Solving Number  Word Problems Series. In this part, we will discuss how to solve various number problems.  Note that some of these problems are not really number problems per se, but the strategy in solving them is technically the same. You could say that they are really “number problems in disguise.”

We already had three problems in the first part of this series, so let’s solve the fourth problem.

Problem 4

If 8 is subtracted from three times a number, then the result is 34. What is the number? Continue Reading
