Do
You Remember Algebra From School?
Do you remember algebra from school?
x=5, y=6, z=x+y
Do you remember that a letter (like
x) could be used to hold a value (like 5), and that you could use the
information above to calculate the value of z to be 11?
These letters are called variables,
and variables can be used to hold values (x=5) or expressions (z=x+y).
