Issue 1a Spring 2015
Welcome
to the first edition of the Skippers Mathematics
newsletter.
Although this edition was produced by myself, it is my intention that
subsequent editions should be compiled of entries from you.
The aim is to provide maths to you beyond the classroom setting, to inspire
curiosity. Contents will include items about number relationships and geometric

properties whilst providing you with some history and amazing facts.
We hope that you will find it informative, interesting, fun and challenging.
There will be profiles of key people in the mathematical field, competitions,

puzzles and the odd joke or two plus some very useful revision notes to collect.
Competition
I would welcome your input and of course volunteers to help collate and assist in
And just for
producing this newsletter which we hope to bring to you every half term.
fun!

Did you know……………….
The name of the popular search engine ‘Google’ came from a misspelling of the
word ‘googol’, which is a very large number (the number one followed by one
hundred zeros to be exact). 1000000 = One million
1000000000 = One billion
1000000000000 = One trillion
1000000000000000 = One quadrillion
1000000000000000000 = One quintillion
1000000000000000000000 = One sextillion
1000000000000000000000000 = One septillion
1000000000000000000000000000 = One octillion
1000000000000000000000000000000 = One nonillion
1000000000000000000000000000000000 = One decillion

Question: Why is this a mathematical limerick?
( (12 + 144 + 20 + 3 Sqrt[4]) / 7 ) + 5*11 = 92 + 0
Answer:
A dozen, a gross, and a score,
plus three times the square root of four,
divided by seven,
plus five times eleven,
is nine squared and not a bit more.

And just for fun:
When written in words which number is the only number that has
its letters in alphabetical order and which number is the only
number with letters in reverse alphabetical order?
Review- Ipad App
Panasonic Prime Smash!
This game was recommended to me, I like it, but what are
your views? is it useful? Fun? Can you recommend other?
Mathematical apps for us to try?
Question:
The app refers to prime numbers as ‘atom numbers’,
Why do you think this is?

Q: Why is a math book always unhappy?
A: Because it always has lots of problems
Revision Notes (First of our cut out and keep series)
Number
Integer
Is just a mathematical word for whole number.
The thing to remember is that integers can be positive or negative
e.g. 1, 7, 298, -3, 0 and -49 are all integers, but 2.5 is not!
Factors
Are all the whole numbers (integers) that divide into your number exactly
(there must not be a remainder!)
Don’t forget: 1 is a factor of all numbers, and so is the number itself!
e.g. The factors of 12 are: 1, 2, 3, 4, 6 and 12
Multiples
Are all the numbers in your number’s times table (Don’t forget: you must count
the number itself!)
e.g. Some multiples of 7 are: 7, 14, 21, 28… but there are loads more, like 700
and 4445
Square
Obtained by multiplying any whole number (integer) by itself.
Numbers
The first square number is 1, because 1 x 1 = 1.
The second square number is 4, because 2 x 2 = 4, and so on…
eg: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
Triangle
You can get all the Triangle Numbers by starting with 1, and then adding 2,
Numbers
then adding 3, then adding 4, and so on…
So: The first triangle number is 1,The second triangle number is 3 (1 + 2)
The third triangle numbers is 6 (1 + 2 + 3)
eg. 1, 3, 6, 10, 15, 21, 28, 36, 45, 55
Prime
A prime number is a number that has exactly 2 factors, no more, no less
Numbers
So: 1 is NOT a prime number, as it only has one factor (1)
2 is a prime number as it has two factors (1 and 2) is the only EVEN prime
7 is a prime number as it has two factors (1 and 7)
21 is NOT a prime number as it has four factors (1, 3, 7 and 21)
1061 is a prime number as it has just two factors (1 and 1061)
The prime numbers between 1 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29,
31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.
