5+5 <>= 5+9

The expression 5 + 5 <>= 5 + 9 is not a valid mathematical expression. The "<>=" operator does not exist in standard mathematical notation. If you meant to use the "!=" operator, which means "not equal to", the expression would be 5 + 5 != 5 + 9. In this case, the expression evaluates to true because 10 is not equal to 14.
