Hello My Mathematical Friends,

Official Seal of MATHSPIG The President of the United States of Mathematics

The Gettysburg Address, Martin Luther King’s ‘I have a dream’ Speech and Winston Churchill’s ‘We shall fight on the beaches … we shall fight in the fields and in the streets … we shall never surrender’ speech were speeches that inspired millions in difficult times.

Maths needs an inspiring speech.

Why?

Because today too many kids do maths like this:

They sit in front of a computer. They answer questions on a program as if they’re shooting at a target. They don’t care about the maths. They just want to know their score. All very entertaining … but they’re not working their brains. They do not think.

Many do not know their tables even in Year 7.

Maths has turned into a guessing game. And they struggle with it.

Here is the comic take on the problem: Hugo Does His Homework, sort of.

But there is a serious side.

Maths needs an inspiring speech. So listen up Middle School students. Here it is:

Barcode Maths

May 4, 2012

Here is standupmaths comic Matt Parker doing calculations in his head including a bar code calculation.

Thanks to Matt making the barcode calculations look EASY Mathspig spent about 12 hours blowing steam out her ears and tearing up packaging trying to get the barcode maths to work.

This is THE absolute best exercise to test accuracy in simple calculations including transcribing numbers, which are so easily misread. It also shows you how BARCODES work.

The cash register pings if the BARCODE CHECK DIGIT Algorithm matches the CHECK DIGIT, which is the last digit in the barcode. This is how the cash register computer checks that the data in the barcode has been transferred correctly. All data transfers have some sort of data check algorithm.

The PING is KING!!!!!!!!

Mathspigs, you can check your maths skills by picking up the nearest product with a 13-digit barcode and calculating the CHECK DIGIT. The answer is at the end of the barcode.

You can find an alternative explanation here.

If your calculations won’t work use the online CHECK DIGIT CALCULATOR (EAN 13). If it is right check your calculations again!!!!!!
