Part-1:

Heigh-Ho everyone!

(“Heigh-Ho” is how one end up looking 80 years old in an attempt to look 13 years old 🙂  https://en.wikipedia.org/wiki/Heigh-Ho)

By the way, I am Om’s Dad. No, Really, I am.  “You will know this  for sure when you sea grammar & speling miskates in riting” 🙂 🙂

Okay, enough kidding (apart from the fact that I am really Om’s dad), let’s dig right into some boring (wink!) stuff.  Oh, see? I don’t even know how to use wink emoji so had to type ‘wink!’ instead.

Sorry.  Now serious.  Let’s get things in order.  Literally, “In Order”.  Let’s talk about “Order” today – “Order of Operations” that is.

Long story short, why are we talking about Order of Operations?  Oh, it is VERY important and it is VERY hard to understand (wink again! tricked you. it’s not hard at all).  If you don’t know the Order of Operations, you get your ‘Math’ incorrect, you get your ‘Programming’ incorrect, you get your school assignments incorrect (in grade 4/5), you get your whole life….(no scratch that last one.  You always get your life correct no matter what you do, as far as you do it wholeheartedly, and keep values & character you learn from your parents & teachers alive in your heart).

You ask a question: What is “Order of Operations”?  Let’s answer that with an example. Answer of 2 * 3 + 5 is 16 or is it 11?  And answer of 10 – 5 / 5 – 1 is 8 or is it 0?  How do you know what is right?  To get those answers always right, you need to know something called “Order of Operations”.  In other words, you need to know rules about what operation you do in what sequence/order. Meaning what part do you solve first, plus or minus or multiplication or division? What do you do next?, and next? There are so many operations (plus, minus, division, multiplication, exponent, square root, bracket, etc), so how do you remember the sequence in which you need to solve them?  Hard right?  NO.  Easy.

Let’s see how with one fun trick we can always remember the “Order of Operations”, and always get answer of our equation correct.  But promise me you won’t share this trick with your teacher.  Let teacher do it the hard way while you already know the easy way 🙂

The trick is to remember: Push Evil Monkeys Down A Sewer

Now enough for this part of the blog.  I will explain all that in detail, in next part.

I have a gangnam-style song and video to share with you. I have a lot of funny examples to share to show how strange an answer of a math equation becomes when you don’t apply Order of Operations correctly. I have some controversial point about these rules. And in the end, I have some learning resources for you ( nops!, not for you, for your parents actually. Wink! 🙂 ).

Stay tuned.  Keep visiting Team AIRO’s blog where you will get to know new things with fun.

Always stay smarter than your parents as you already are 🙂

googology (what?, what is that?)

For Age Group: grade 3 & up

Hey everyone, and welcome to my blog – again!

This time, let’s start with a question: What’s the largest number you can think of? (No, saying infinity is not allowed). A million? A billion? A trillion? If you wanted to, you could start with a 1 and write zeros until you get tired, and that could be your answer.  But think: There are probably smarter ways to do this. One way would be to only write 9s until you get tired, making your number bigger. Now let’s say you don’t want to keep writing until your hands get tired. You could use multiplication, so instead of writing 1000000, you could write 1000 *1000.

This is the principle of googology: coming up with smart ways to make bigger numbers. For example, some older readers might have thought of using exponents.(For those of you who don’t know about exponents, think about how multiplication is repeated addition. Exponents are like that, meaning they are just repeated multiplication, and they tell you how many times to use a number in multiplication, just like 3*2 is 3+3, 3^2 is 3*3. Another example would be how just like 5*3 is 5+5+5, 5^3 is 5*5*5).

So how did I get interested in a relatively obscure field like googology? It all started when I was young, and I had come across a webpage explaining Graham’s number (You can research Graham’s number on your own, asking your parents for permission first, of course, but to put it in simple terms, it’s really, really big). I was fascinated by the idea of a number that insanely large and started wondering if there were bigger numbers. This led me into a spiral where I discovered a wiki made specifically for googology, and started learning more about it. (I actually got the idea for this blog by finding something I wrote about googology in my third grade notebook, next to the word “quack” repeated over and over again).

So why would you learn googology? Later in life, you might encounter some particularly hard math problems, and you’re going to end up with a really big solution and so you’d need to know a way to notate that. In addition, searching for the largest number can help hone your math skills and help you discover new principles that you might use later. For example, some of you probably learned about exponents by reading this blog about googology.

By the way, this is the video that started my obsession with googology:  https://www.youtube.com/watch?v=XTeJ64KD5cg&feature=youtu.be

And for your amusement, this is a joke article about googology: https://sites.google.com/site/largenumbers/home/appendix/e/easter (Don’t worry if you don’t recognize some words, or you see a fact you don’t think is correct; a lot of words are made up, and it is just a joke.)

Have a great summer everyone. Hope you are enjoying the good weather so far.
