B is interpreted as a plus b where the plus.
One equals sign in ruby means assignment make sure to use when you want to find out if two things are the same.
With an if statement you can check if something is true.
Operator name example result equal.
Comparison returns 1 0 1 or nil depending on whether string is less than equal to or greater than other string.
But when you want to check for the opposite not true false.
If the strings are of different lengths and the strings are equal when compared up to the shortest length then the longer string is considered greater than the shorter one.
While evaluating the expression a a ruby will actually create two different string objects which both contain a single character a.

Notice that we use two equal symbols to mean equality.
The text within the quote marks is the value of the string this is a simple ruby string literal.

Ruby size 4 you can also use length instead of size they do the same thing.
True or false basis on the equality.
Nil is returned if the two values are incomparable.
Most operators are actually method calls.
The simplest string literals are enclosed in single quotes the apostrophe character.
True if x is exactly equal to y not equal.
