# ………………..How much money does a popular

You will learn everything you need to know at 1 Million YouTube Views.  Now let’s do the maths!

Here are the TOP 3 YouTube Clips Ever. Their popularity is measured by Number of Views.

YouTube uses an algorithm (ie. a formula) for calculating the amount of income earnt by a clip from advertising. There are multiple issues involved including how long viewers watch the ad, the demographics (age group) and the actual sales (Retailers actually do review ad costs vs increased sales. Always. They are not idiots.)

Here is  the basic method used to calculate ad revenue for a Youtube creator. Remember, a creator must have a minimum of 10,000 hits on their channel before any revenue is paid.

Of course, pop stars use Youtube as a promotion platform. They can earn money through multiple Youtube clips, sponsors, merchandise and live perfomances. Nevertheless, it is surprising how little money is earned by each clip.

eg. ONE DIRECTION

# The New Age of Guess-amatics!

Hellooooo Sweeties,………………………………………………………………………

Some frightening maths this week. When researching DANGEROUS MATHS, Mathspig found one branch of maths is the most dangerous maths of all. Let’s call it GUESS-AMATICS. Today, maths is often taught via computer program packages. Some of these computer packages turn maths into a guessing game.

This exact and rather frightening scenario was described to me by the mother of a 5 year old. The mother decided it was time to turn the game off. When students play mathematical computer games too often they don’t have to think, they just guess the answer and try again. But be warned this ‘Oops! Try again’ maths can kill you’! Some maths you cannot ‘try again’. You HAVE to get it right the first time. Medication is one area where ‘Oops! Try again maths kills”

# Do the Maths and Do NO HARM.

You need sufficient maths to understand medication doses or you might do yourself harm.…………………………………………………………………………………..

And here is just one very frightening statistic:……………………………………..

According to FDA data 1.3 million people in the USA are injured each year from medication errors.

Meanwhile, we need nurses, caregivers, doctors, paramedics, First Aide volunteers, parents, grandparents, babysitters, teachers and all health care professionals to have sufficient maths to be able to calculate simple medication doses. Or we need them to simply READ the dose and make sure it is correct. Unfortunately, many of those who should be able to work out medication doses are either incapable or not paying attention. And your life could be in their hands:

# UK

In the UK 1 in 20 hospital deaths is due to medical error. Nearly 12,000 patients die needlessly in hospital every year due to blunders by staff, researchers warn. Drugs or fluid mismanagement  was identified as a problem in 21% of preventable deaths (NHS   2012) or, doing the maths, 21% of 12,000 is approx 2,500 deaths due to bad maths!

# USA

According to a new study just out from the prestigious Journal of Patient Safety, four times as many people die from preventable medical errors than we thought, as many as 440,000 a year.

Reports show between 9,000 and 24,000 hospital deaths due to medical error.

# Australia

Official Australian government reports reveal that preventable medical error in hospitals is responsible for 11% of all deaths in Australia or 1 in 9 deaths.

## Dangerous Maths 1:Young drunk dead

August 26, 2015

Statistics for alcohol consumption are tricky. Binge drinking gets confused with heavy drinking. If you want to stay young go to the UK. They think anyone under 35 is a youth! Some stats separate Male and Female drinking habits. Some don’t. And legal drinking ages vary. Canada is one crazy place. It has different legal drinking ages in different parts of the country.

# The Maths

What we are working on here is reading maths data. No lectures. The numbers speak for themselves.

Graph source here

# The Challenge

Find the following information from data below. Percentage of Year 12 students or 18 year olds who binge drink in each country below.

# 1. Australia

Alcohol related death stats over lap other stats including death involving cars, motorcycles, bicycles, skateboards, jet skis, quad bikes, drowning, diving, stairs, supermarket trolleys and even high heels.

# USA4: 4,358

1. 15-34 years for 2011. Source
1. 15-24 years average 1990-2002 Source
1. Under 18 years of age. 1996 It is believed that as many as 83 percent of teenagers in Canada consume alcohol. Back in 1996, underage drinking was responsible for 3,500 deaths and 2,000,000 injuries. A 2002 survey found that 20 percent of eight graders had consumed alcohol within the previous month. Source
1. 4,358 people under age 21 die each year from alcohol-related car crashes, homicides, suicides, alcohol poisoning, and other injuries such as falls, burns, and drowning. Source

These countries have different populations (See post below). USA population is 15 times Australia’s. 260 x 15 = 3,900. So the Aussie and US stats are in the same ball park even though the stats have been collected for different age ranges. But look at Canada. The USA population is about 9 times Canada’s. 4,358 ÷ 9 = 484 deaths. This  death statistic for Canada is 10 times larger than the USA statistic per head of population. Meanwhile, the population of Canada is 1 1/2 or 1.5 times Australia’s. 260 x 1.5 = 390. Once again, the Canadian statistic is out by a factor of 10. What’s going on here?

# The Bar Where You’re Too Afraid to Get Smashed

Mathspig is a party pig. But why does anyone drink themselves senseless? Many reasons, but one is they’re bored. Now here is a bar in Mathspig’s home town, Melbourne, where you better stay sober. Break out of prison in Trapt Bar. You’re in prison, you’re innocent, and no one believes you. You plot an escape with the other prisoners–because unless you break free soon, you’ll all face an unspeakable death (this prison is off the charts). At Trapt Bar and Escape Rooms, you and your teammates have 45 minutes to find clues, solve puzzles and escape before…well…let’s spare you the gruesome details.

## Dangerous Maths 2: Death by Snake, Spider, Quad bike, Kangaroo, Raccoon and Vomit

August 7, 2015

This post is really a PR exercise for sharks. We fear them. We’re horrified by the thought of being eaten alive!!!. We only have to hear the sound track from JAWS to feel the fear.

Why do we fear sharks? Look at the numbers. REALLY. Show your students. What about stairs??? Quad bikes? Chairs? Bees? That’s when you should feel the fear!!! We are irrational beings. This is why we need maths. We can make rational decisions using maths. There is also a safety message here. The maths speaks for itself. We won’t hammer it.

# THE MATHS:

There is lots of maths you can do with these tables.

• Bar Graphs
• Pie Charts
• Ratios (What’s the ratio of death by Snake to Quad Bike?)
• Fractions (Show death by jet ski to falling down stairs as a fraction)
• Percentages
• Powers to the base 10. How many deaths occur in each country per 100,000 or 1 x 10head of population for, say, Quad bikes or ATVs? We can use these numbers to compare death rates and find out how dangerous riding a Quad bike is in each country.

……..Population Data

……..Aust…23 million = 23 x 106

……..USA…319 million = 319 x 106

……..Canada…35 million = 35 x 106

……..UK…64 million = 64 x 106

But we’re doing this for the SHARKS!!!

1. Cyclists. 2. emergency lanes 3. fell off a chair 4.QUAD BIKES. 5. Horse, donkey. 6. buses 7. Cow, bull. 8. ice skates, skis or skateboards. 9. Venemous snake 10. kangaroo 11. bee 12. emu 13. Jet ski 14. Shark 15. Crocodile

1. Quad Bike or ATV: In 2007, 107 children younger than 16 were killed on ATVs. 2. Cyclists 3. choke on vomit  4. Cats, cows, horses, pigs, raccoons. 5. Bees, wasps  6.PWC or Jet Ski 7. Lightning 8. Xmas tree fires 9. Snowboard 10. Venomous Spider  11. Scorpions 12. Venomous Snakes , lizards. 13.Crocs & gators  14. Shark

1. ATV Quad Bike 2. Canoe  3. Kayak 4. PWC or Jet Ski  5. Unpowered inflatable 6. Avalanches or landslides. 7. Lightning 8. Toboggan 9. Moose –Car collision 10. Bears (All Nth America) 11. Rattle Snake 12. Wolves 13. Shark

1. falling down stairs.  2. Cyclists.  3. Choke on vomit   4. Falling off Chairs 5.  QUAD BIKE or ATV 6. Buses 7. Struck by cow, horse, other mammal 8. hornets, wasps, bees. 9. PWC or jet ski .10. Parachutists. 11. Skateboards, ice skates, skis 12. Canoe. 13. Shark

Hellooooo My Little Sweeties,

There is so much maths you can do with m&ms, it’s hard to believe there is any other sort of maths.

You can study:

Fractions, % and decimalsand parabolas (using a really cool peg-powered catapult).

But my favouritest ,developed by Patrick Len, is using m&ms to demonstrate half life in radioactive substances and therefore write an exponential equation.

# m+m ACTIVITY:

Throw a fixed no. m&ms on a table. Mathspig chose 128 m&ms for a very good reason. Eat the ones with the m showing. Count remainder. Throw again. Eat the ones with the m showing. Count remained. Keep doing this. You will end up with results like the following. (Not identical as chance is involved)

Wow! m&m’s and exponential equations. How yummy is that!!!!!!

More yummy maths:

m+m maths 1: find the volume using m+ms!

m+m maths 2: Guess, NO, calculate the number of m+ms in a jar!

m+m maths 3: how many m+ms will kill you?

m+m maths 4: How many m+ms will kill my dog?

m+m maths 5: how many m+ms will kill my cat?

m+m maths 6: How many m+ms will kill my pet rat?

m+ms maths 7: how many m+ms will kill my pet mouse?

Mmmmmmm! Can’t talk. Face full of chocolate.

Bye bye

## Are you bored by doing volume calculations?

Are you looking for a new and exciting way to calculate the volume of, well, things maths teachers ask you to calculate the volume of? Like what? You know, cubes or cylinders or cones or stuff. Well, today mathspiggies, we have the perfect solution for you. Yes!

We will calculate volume by counting m&ms!!!!  Do I hear any complaints???? Anyone!!! Right!

# WARNING: You may need a ship load of m&ms!!! Just saying.

Mathspig salutes CWanamaker for doing maths over and above the call of duty by actually measuring how many m&ms fit in various containers. He has provided us with the RPR (RAndom Packing Ratio) for m&ms(below) and you will find his experiments here.

Two things you may need to know:

## 1cm3  = 1 ml

If you are like me, mathspiggies, you will be amaaaazed how many m&ms it takes to fill, say, a coffee mug. Nevertheless, you can calculate the volume from the no. of m&ms and you will find the answers here

## m+m maths 2: Guess, NO, calculate the number of m+ms in a jar!

July 6, 2015

Of course, mathspiggies, we can do the reverse maths and cheat … and use our superior maths skills to calculate the no. of m&ms in a cookie jar and then you WIN the cookie jar full of m&ms at the school fair.
