Learn the Meaning of Multiplying Decimals - [13]

View more at www.MathAndScience.com. In this lesson, you will learn the concept of decimal multiplication. We will use models and pictures to illustrate what it really means to multiply a decimal by another decimal. The second number functions to chop, or cut, the original number into a smaller number. We graphically show how to use this to multiply decimals and show that the answer makes sense intuitively. In later lessons, we will show the steps to multiply the decimals out by hand and how to place the decimal point in the final answer.

It's kinda gross that I was not taught it as intelligently as this. Here is the explanation I got from the schooling: Take the first number, and put it in the calculator. I knew they were fractions and parts, but what was the calculator doing? What was it showing me? I never knew until now. You are a gem sir, I appreciate you.

[@mathsandsciencechannel]

Thank you sir. You have been the inspiration behind maths and science channel

[@LQVEGA]

What a very nice explanation, sir..students who are having hard time multiplying decimal numbers, will understand it easily because of your clear and concrete explanations..

[@MathAndScience]

You're most welcome!

i realize I'm pretty randomly asking but does anyone know a good website to watch new tv shows online ?

@Kaison Brett Thanks, signed up and it seems like a nice service :) Appreciate it !

[@kaisonbrett755]

@Xander Vance Glad I could help :)

incredible clarity and very engaging!l im in HS but never knew this. I like the analogy of 'chopping'

[@xbluebells]

This put tears in my eyes as I remember the frustration with learning math many moons ago and nobody really having a way to explain to me math in a way that made sense. It seems like until I can understand WHY something makes sense it was hard to do the mechanics so you match my learning style so much. I wish I could go back through my math training and learn it graphically. It was not until pre-calculus and I saw the equations being graphed that a light bulb went on in my head and I saw that math could be meaningful and exciting to me. Thank you from the bottom of my heart. Also exciting to see how really I could use your technique to multiply 16 x 5 in my head. I don't know but I do know that 16 X .5 = 8 so that would mean 16 x 5 should be 80! I can do that in my head. I never knew I could do math in my head that way!.

[@MathAndScience]

Wow thank you so much! I love this comment!

[@samabreez8746]

Oooh the 16×5 is incredible

[@patienceankrah4219]

Thanks for inspiring me to learn math. I use to dislike math because I didn't understand it

[@adambakas13]

This guy explains math. I wish other teacers would explain math instead of just assuming you already know the math.

[@johncharles81]

Wow good lesson I really enjoyed that, and can really use what I have just learned .👍👍

[@MathAndScience]

Awesome! So happy to hear this!

If there is a math genius it is you , sir.

God Himself explaining His Own creation. Grateful Sir.

[@chinmoyee.....2944]

Really a very nice explanation, thank you sir. 😇😇😇

[@MathAndScience]

So nice of you!

[@hentaimami2626]

Sir Gibson, First and foremost I would like to thank you for helping me gain confidence in Mathematics. It is a subject I have always loved, but never truly grasped the fundamentals, so I flunked it all throughout High-School. 1yr out and I stumbled upon your course. Purchasing it has been the best decision I have made, halfway though the Algebra1 course and I can't believe concepts that I thought we're difficult are a piece of cake now. Can't believe math was this easy alll along. Can proudly say I am almost always looking forward to the next lesson and doing the quizzes and extra practice. Something I'd always skip in High-school, because it was so frustrating to not understand. Looking forward to any courses you roll out in the future!❤

Brilliant, thanks Jason!

Am in finance industry buh never knew this,, thanks alot teacher

[@georgiaaggrey-fynn7768]

Sir Jason thank you 🤑

You're the best teacher I never had, Jason. Thank you so much!!!

[@aliciapimentel9709]

Thank you Sr. Exelente.

[@MathAndScience]

You are very welcome

[@omegamath5125]

Definitely Good in the area of positive numbers.

[@clarencevinuya6158]

Thanks u for this

[@alexzhou4440]

@math and science Can you make videos on stem? Like for example, spatial ability folding shapes using ur head. Thank you

[@MathAndScience]

That is something definitely interesting to think about!

[@ShiraGoldberger]

Can you explain why the answer to 0.2 x 0.3 is .06 and not .6?

[@someday5448]

You have an amazing ability to clarify concepts and make it practical. Thank you!

[@MathAndScience]

Welcome and thank you so much!

[@memorizer4941]

This is such a great way of showing it; many people could benefit from this (and all your other videos)!

[@MathAndScience]

Thank you I sincerely appreciate it!

[@memorizer4941]

@@MathAndScience you’re very welcome!

[@georgiaaggrey-fynn7768]

These are easy because you just need to times the last number not the 0

[@imkadosh]

Say it this way: multiplication by decimals, decreases Multiplication by whole numbers above 2, increases

[@ErickTun]

I have been multiplying decimals most of my life and this is the first time I've been able to visualize what that means. Thank you for the excellent explanation.

[@exe.m1dn1ght]

Is this right how I understand ? basically 0.4 x 0.5 is 4 pieces (fractions) and i split every piece, and i get 5 pieces for every piece (4 groups of 5 pieces each) , and those 5 pieces represents 5 hundreths, becaue they are smaller than those 4 'whole' pieces which i started with, so finally i got 20 pieces in total and i need 100 to make a whole so its 20/100

[@hemarajue2736]

This decimal multiplication through graphs better explains the concept underlying it. I think multiplicand is represented by horizontal lines,multiplier by vertical lines and the product by overlapping area. One common mistake while performing decimal multiplication is ignoring the decimal points. Actually they count in the multiplication. For e.g 0.2×0.1=0.02 and not 0.2

[@MathAndScience]

Yes!

[@liamhoward2208]

Or you can think in percents if it’s easier. 50% of 40% = 20%

[@imkadosh]

I feel sorry for children because this philosophy is not taught as it should be taught. Only old fashion teachers know how to. This is where the gift of teaching comes into play.

[@gavinirwin9675]

What are you talking about the two should be in the hundredths place when you multiplly0.4×0.5

[@manyatanamdeo2046]

Hii

[@MathAndScience]

Hi!

[@johnjacobjinglehimerschmid3555]

Sweet lord.... What about multiplying do you have to not get for this to make sense? I was hoping that there would be some revelation about why the std multiplication works. I know how to multiply by decimals and I'm ripping my hair out trying to understand this.
