Blog postWhat is A+ Content? In addition to the product page (and in addition to pages that you can access from Author Central, like the author biography or a From the Author section)…
A Plus Content lets you add additional sections of writing or images to help showcase your book or provide more information about yourself.
It can be a sales tool that you put right on your Amazon product page.
There are several formats to choose from, such as a single wide image (with or withou -
Blog postKINDLE VELLA Amazon just launched the new Kindle Vella.
What is Vella? Stories that are told one episode at a time. It has to be new content (not content that has been made available previously), so there shouldn’t be material that you’re familiar with from the past that gets repackaged in Vella. There should only be fresh new content.
There are a few points regarding Vella that appeal to me:
Customers can read the first 3 episodes for free. This is basically equivalent o -
Blog postVella is coming soon.
Writers will publish stories in episodes. A single episode may be anywhere from 600 words to 5000 words.
Readers will read stories one episode at a time.
One neat feature that I like is that the author can include optional notes at the end of each episode. An author might share insights into how the story came about or share a personal note. There are many ways that authors can use this space.
Ordinarily, when you read a novel, such notes -

Blog postAUSTRALIA KDP Amazon’s Kindle Direct Publishing (KDP) is finally opening a print-on-demand (POD) facility in Australia, which is great news for authors, small publishers, and Amazon customers in Australia.
The new facility is set to begin its launch on May 19, 2021.
KDP authors should check their paperback pricing options starting on May 12, 2021. On this date, you will be able to check your list price and royalty for Australia, and if necessary, you can adjust the list price -
Blog postXL Book Stand My neck was sore from proofreading and revising. Tired of looking down at an angle, I wondered if there was something I could stand atop my desk that could hold books and papers more at eye level. I found this cool book stand on Amazon.
Book Stand I bought the XL size (15.4″ by 11″). I set my 1700 page Webster’s College Dictionary on this, opened to the page I’m using, and it supports it just fine. I also print out my manuscript and set it on the book stand, and it w -
Blog postRECENT CHANGES AT KDP There have been several changes to Amazon KDP recently. Have you noticed?
SERIES. One interesting change is the introduction of the series page and the series manager. It seems like this new tool isn’t 100% complete yet, but it’s a giant step in the right direction. From the publishing end, it makes it easier to manage series. Now you get a series landing page and you can even write a series description (by default it uses the description from the first book). < -

Blog postSINE, COSINE, AND TANGENT OF 15° AND 75° It is possible to find the sine, cosine, and tangent of 15° and also 75° without using a trig identity (and without using a calculator).
The trick is to begin with a 75°-75°-30° isosceles triangle, as shown above. Let AB = AC = 2. These are the sides opposite to the 75° angles. The remaining side, BC, is unknown at this point.
With side AB serving as the base, draw an altitude down from point C, as shown -

BEWARE OF BOOK PIRATES Earlier this year, after publishing a new book, I visited Amazon to check it out. When I finished inspecting the Amazon detail page for my new book, I clicked the link by my author photo to visit my Author Central page. And, boy, was I surprised by what I found.
(A little background: Author Central now shows only my Kindle eBooks by default. Customers have to click the Paperback tab to find my paperback books.)

Blog postEXPANDED DISTRIBUTION Amazon KDP now offers two Expanded Distribution channels. In addition to the usual Expanded Distribution channel for the US, they have added an Expanded Distribution channel for the UK.
Authors and publishers using Amazon’s Kindle Direct Publishing for paperbacks may now add the Expanded Distribution channel for the UK. Each title must be individually enrolled. To sign up for Expanded Distribution in the UK, find a book on your Bookshelf, and go to Page 3 of the -
Blog postCHANGES AT AUTHOR CENTRAL If you haven’t already done so, when you next visit Author Central, it will ask you to sign up (even if you are already signed up). This part should be easy. It found my previous information and quickly transferred it over. I checked my biography and author photos, which were the same (although I noticed a couple of duplicate photos and deleted the duplicates). At first, it seemed like my blog feeds were missing, but when I proceeded to add them, I saw that they wer

Blog postHere you can find the answer key to Division Facts Practice Book by Chris McMullen, Ph.D. This practice workbook is part of the Improve Your Math Fluency series of workbooks. Most of the workbooks in this series contain the answers at the back of the book. However, the original editions of the basic facts books did not contain the answers. By request, I am adding the answer key for the Division Facts Practice Book to my blog. Here you will find just the answers (not the problems).

ESSENTIAL CALCULUS SKILLS You learn a lot during a calculus course.
How much of this is useful?
Of course, it depends on what you do after calculus.
For example, much of the material is needed in higher-level math courses.
But how about for physics, engineering, and other applications of calculus?
derivatives of polynomials and trig functions are absolutely essential. You need to practice these until you’re fluent. for integration, sometimes -

Blog postCHECKING YOUR ANSWERS: Many math books post the answers to selected questions in the back of the book. Most of my workbooks include the answers to every question in the back of the book.
A few students get a different form of the same answer, and mistakenly believe that the answer in the back of the book is wrong, when it’s really correct.
One common example occurs when the student gets a squareroot in the denominator, like:
The above answer isn’t in standard form. Mo -

ESSENTIAL FRACTION SKILLS Not everyone loves fractions, but fraction skills are important for a number of reasons.
It helps to be fluent with fraction skills when you take algebra, trigonometry, and calculus courses. When you solve for an unknown in algebra, the answer doesn’t always turn out to be a whole number. One reason that cross multiplication is difficult for many students is that the problems inherently involve fractions. In calculus -

Blog postPOWERS OF 10 What are powers of 10?
How do you multiply or divide powers of 10?
What are negative powers of 10?
What is 10 raised to the power of zero?
Compare positive and negative powers of 10. Note that the number of zeros is a little different with positive and negative powers of 10. See the chart below.
Examples:
Teachers (and home school educators or parents) are welcome to use the above material regarding powers of 10 for non-commercial -
Blog postBlock Sliding Down an Inclined Plane Consider the block sliding down an inclined plane (with friction) illustrated below.
When we apply Newton’s second law to the box, we set the sum of the x-components of the forces equal to max and the sum of the y-components equal to may.
One of the forces is weight, which equals mg (mass times gravitational acceleration).
The x-component of mg has a sine function, whereas the y-component of mg has a cosine function:
(mg)x = mg -

However, in physics, these two words have very different meanings:
An error is something that affects results, which was not plausible to -
Blog postUSING ALGEBRA IN ARITHMETIC It’s interesting that algebra can be useful in arithmetic.
Since arithmetic is a prerequsite to learning algebra, most algebra courses don’t focus on how to apply algebra to do arithmetic.
However, you can apply your algebra skills to arithmetic problems.
Following is an example.
Suppose that you would like to multiply 58 times 58, but don’t have a calculator (or cell phone) handy.
One way to do this, which is often taught i -
