Easy Percentage Trick you were Never Taught at School!

This percentage trick is so easy - but you probably don't know it...because, let's face it, you were not paying attention in school when the teacher told you!
That's OK - youtube and tecmath has your back - with this, the easiest percentage trick you were EVER taught in school!

I've been teaching math and science since the late 90's and I can not believe I did not know this awesome little trick. I can assure you that this technique WILL be taught at school from now on.

I've been using tricks like that all my adult life without even thinking about it. Mental arithmetic is mostly about looking at a difficult problem from a different angle.

I'm 68 yrs. Old. The older I get, the more I realize how much I don't know. Your teaching is a wonderful gift. I have 8 school aged grandchildre. We sit together and watch your videos. Not all together at once, these guys have so much energy. They come to me and show me what new things you've taught them. They are doing quite well thanks to you. I thank you so much! Jerry

I’ve never had a problem with percentages, and thought that I knew enough that I needed, but this one is totally new! Thank you so much!

Great trick, man. Where were you 40 years ago when maths was beating seven bells out of me?

I had the dreaded 'math phobia' in school, I could blame all kinds of things but that was just the result it had on me, I think emotion plays a bigger role in learning than is commonly accepted. Good math teachers know how to present each stage of learning calmly and with assurance-I think this affects millions of people.

Holy moly! I am super impressed with the first % trick….The more you understand the more you want to achieve ! Fab lessons !

[markpennie]

So why don't they teach this at school. Would have saved me so much time and brain cells

[Sarah-tkms]

I was paying attention in school; however, the teachers didn't teach this trick or didn't know this trick. Thank you for this video.

I laughed when I watched this post! Fantastic. Had a ‘no way’ and an ‘of course’ moment at the same time!

Having been out of school for decades this literally was a treat because my brain froze when I 1st saw it....Ty

Thank you. My grandfather used to show me maths shortcuts, however he's been gone a long time. Subscribed.

When I was at school about 14 or 15 years old, the math teacher used to just read out equations for us to solve and see who shouts out the answers first. There was a kid who was really fast. Before I could write down the numbers, he already got the answers. The teacher never explained how those answers can be obtained so fast, maybe she just assumed this kid is some kind of genius. I was far from a genius, but I was and still am CURIOUS. I thought there must be some "tricks" or techniques. I often figured them out myself later.

I'm not generally a fan of maths tricks because mostly, even if the process is simple, you forget how it works if you don't use it regularly. But this is so obvious that it is essentially unforgettable and very helpful.

[pottedmeat]

I'm totally math illiterate and it took me three plays of this video to comprehend the lesson completely - but I do/did get it. Now hopefully I retain it, because it is really a simple way to figure out percentages. Thanks!

[msudlow]

I have never done well in math, but this was an incredible help. Thank you so much.

[Zyxak]

55 and I'm still learning. Bravo!

[MrArtVein]

I remember accidentally doing this in elementary school and being told I was wrong but I still had the right answer. It was all downhill from there

[NomoreAB]

Outstanding! Clear and simple explanation. Perhaps remote learning is the way to go.

[johnhumphries]

So simple yet fascinating. Thank you so much for sharing this bit for my benefit.
