Binary Arithmetic - Counting in Ones - Robin McLean

28th February 2015
Suppose we have one of each of the following weights:

32oz, 16oz, 8oz, 4oz, 2oz and 1oz.

Can we weigh any whole number of ounces?

e.g. 43oz = 32oz + 8oz + 2oz + 1oz.

Are there any other ways of making 43oz with our given weights?

What about other weights from 0oz to 63oz?

We will look at how this question relates to binary arithmetic and explore some applications of binary.
