Summary of what we've done:

- Computers work with bits. Groups of these in fact (32-bit is common at the moment). We though are not particularly interested in bits.
- Using bits we can represent numbers, which we are interested in.
- Storing numbers in binary is the natural thing to do BUT this is limited
because:
- The largest number we can store is only around 4 billion which is not big enough.
- We are unable to represent fractions.

- We can write numbers in scientific notation. Where we break them into a mantissa and an exponent. Using this approach we can allocate some of our 32 bits for the mantissa and the rest for the exponent. Then we can represent VERY LARGE NUMBERS and FRACTIONS.
- Using floating points(the mantissa and exponent approach) we only actually have the first 7-8 decimal places of a number. For example if you add one to 10 billion on your calculator and then subtract 10 billion you get zero and not one(in many cases). So things are not as good as they might seem, but they really aren't too bad.
- Otherwise we looked at how you can convert to octal and hex from binary quickly and how to express fractions in binary.

- Intro to mathematica, overblown calculators. Basically it can perform a vast array of operations. In maths, classic questions involve finding roots to polynomials, differentiating and integration things, working with matrices and vectors and more. Mathematica can help in doing these which means that you don't have to worry as much about learning how to them(If you are a non-mathematician that is).

What you should be able to do:

- Determine what a number written in some base is equal to in base 10.
- Express numbers given in base 10 in other bases.
- Know how numbers are stored on computers(integers and floating points).
- Know how binary numbers can be converted to octal and hex, and vice versa.
- Express fractions in binary.
