The $"-"($minus$)$ and the $""($not$)$ are also referred to as "Unary" operators and may be used in arithmetic expressions. When used in this way, they apply to the value immediately to their right, BEFORE it is evaluated in the expression.

In arithmetic expressions, the null string is evaluated as a zero, while in logical expressions it is evaluated as a False. For example, the expression

$1$

is evaluated as a null; when it is used in the arithmetic expression

$1+1$

the value of the expression would be $1$; but when used logically in the expression

$0=1$

the expression is False. Other examples:

$-3=-3$

$1=""$

$10+0=0$

$2+3+3*-3=-15$

Question. Which one of the following expressions is False?

$1.1!2!4!8$&$15+0=0$

$2.-5-5=2+8*-5$

$3.1+(-3)>4$

$4.(5)=5$

$5.4+4=4+4$
