Exactly the same reason we use them in normal language, 
so that the reader (in this case the PC!) can understand 
what we are trying to say. Thats also why we use capital 
letters at the start of sentences in most languages like 
English, it helps the reader understand whats written 
more easily.

Similarly computers like us to spell things carefully 
and use the right grammar, just like a normal language 
(this is a problem for me because I type too fast for 
my own good and make lots of mistakes!).

So treat the computer like a very literally minded 
English teacher who won't tolerate any spelling or 
grammar mistakes and you'll get along just fine!

Then to understand what you need to input to create a 
program you need to think a bit like a math student 
doing algebra. Lots of variables and math operations 
and grouping of values in parentheses etc.

Itsnot rocket science just the basics of English and 
Math that you get taught in junior school. But basically 
computers aren't very bright so programmers have to do 
their thinking for them!
