Your videos are always fun and engaging. They get me to reach back across the chasm of several decades to math classes, reconnecting my brain to information that has been slumbering for much too long.

Thanks, Suzanne. You’re such a delight, and brilliant too. I always learn something new.

@jmcdermid

I did sqrt(.36) = .6
Then .6 - .06 = .54 = 54%

@x364

How did I not happen upon your channel until now? This is brilliant!

@terencemeikle534

What I love about this is that, on the surface, it looks completely paradoxical. 👌

@danp7201

Suzanne, you are a wonderful teacher - I wished I had you for a teacher when i was at school.  Thanks a lot.  Love your videos - keep them coming.

I was thinking just that - that the square root of some amount lower than 1, yet greater than 0, would actually increase.  But I didn't understand the rules for doing so until today.  So the square root of 0.36 is actually 0.6.  The fractions make that clearer.  Thus the square root of 0.25 would be 0.5, the square root of 0.49 would be 0.7 and the square root of 0.64 would be 0.8.  The difference in value between the square and the square root would actually shrink as we increase and approach the value of 1.  That's the opposite of what happens after increasing beyond 1.

Guten tag, Suzanne, I did get this one, but it took me about 60 seconds. Most of which was thinking about how to calculate sqrt(0.36) before realising I could do sqrt(36/100).

@noGodsNeeded

You are a fantastic teacher!

@racingfortheson

I did it by moving the decimal over two spots. 
(Square root .36) - .06 =
.6-.06=0.54 
54%

@عبدالواسع-س8م

Thanks so much !

@rossk4864

Yes, instantly, but mustn't get confused by the percent sign! Great little puzzler!!

Hi Sussane,

Thank you for posting your videos. I'm well past high school, but I still find your content entertaining and thought-provoking. I know that this method is commonly used in math now, but it wasn’t in my high school days.

I don’t quite understand this percentage concept the way it’s often explained. I don’t think 54% simply equals 54/100. Rather, I believe 54% represents 54/100 of a number, not a standalone value. For example, 54% of 10 is different from 54% of 15.

I’m not sure if I explained my point clearly, but my understanding is that you shouldn't be able to add, subtract, divide, multiply, or find the square root of a percentage by itself—you need a reference number.

@A77uros

My advice is that never calculate in percents, always change them to fractions or decimal numbers before any calculations, this way you avoid many mistakes. 😀

@AbercrombieC

Brilliant!

@swentac4497

Your delightful videos are the best of my day!

@djparn007

Thank you, Susanne. ❤❤❤❤

@mathacademy-u6t

nice interesting math.its realy math good trick❤❤❤

@Mario_at_Me

the English version of your math channel is just as great

@ElvisSaturn

6/10 - 6/100 = (60-6)/100 = 54%
