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 🙂
