Today’s word is Base

To a mathematician I’m transported back to my classroom.

Here are 100 additions. All of them are correct; what’s the ‘trick’?

1 + 1 = 10

11 + 10 = 101

1 + 1 + 1 = 11

101 + 110 = 1011

So, what’s the trick? I’m using **binary** or **base 2**. Us humans use base 10; probably because we have ten fingers. Computers use base 2; because they use electricity which can be on (1) or off (0)

In base 10 the place values are

… thousands hundreds tens units

Each place is worth 10 times the one before. A hundred is 10 squared, a thousand is 10 cubed and so on…

in base 2 the place values are

… eight four two units.

Each place is worth 2 times the one before. Four is 2 squared, eight is 2 cubed and so on…

100 questions is 4 in base 2. Check the questions to see if you get the idea.

**There are 10 types of people in the world. Those who understand binary and those who don’t.**
