Numbers and strings (text)

In really basic Javascript if you set a variable equal to a number, you need to make sure the number is not inside brackets (” “).

This could cause the following problem:

x=5+5;

x=”5”+”5”

If you gave the order to:  document.write(x); in the first example it would equal 10 in the second it would equal 55.

There’s actually a rule here if you add a number to a string the result will always be a string. so:

5 + “5” will equal 55 as well.
