## The Challenge that Failed Me

The Math Challenge Plugin I used to employ to combat comment spams generated by spam robots failed me. And that is the reason why I’m dumping it.

I’m not exactly sure whether the comment spams that entered my akismet filter were posted by individuals, because there were so many of them, or the plugin must have just been defective. Nevertheless, I’m removing it and instead, have spam karma 2 purge those spam after 2 hours. Yeah you read it right, 2 hours. I may not even have the time to review those comments whether there are valid ones erroneously filtered by the two comment spam plugins.

Now, then, I would like to request my commentators who may find their comments not able to come through in the article they are commenting on to notify me via the contact page. This is very important and I want you to know that I value your comments very much that I don’t want them lost.

Moreover, I can now re-activate other javascript plugins like post-ratings, etc., that I once deactivated to give way to this inutile plugin.

## The Math Grid

It has been say almost 20 years since I first learned arithmetic. Yet, I could still feel the agony of solving those 100 items each for addition, subtraction, multiplication, and division.

Almost the same items or questions were given from grade 2 to grade 4, yet I only mastered arithmetic on the 4th grade. Of course, the most complex of the four process is multiplication, especially when it involves 2-digit factors (multiplier or multiplicand, see i can still remember those terms…:LOL:), much more with higher-digit factors.

Well, the diagram below offers an alternative way of solving multiplication probles involving 2 or more digit factors. Easy? Yeah, I think it’s interesting.

PS: Did you know what helped me become quick at addition when I was yet learning arithmetic? It’s a secret, ok? I used to play “Lucky 9” when I was small…:LOL:
