Multiplication and Division of Signed Mumbers: Multiplication of a negative number by a neutral number

Let's remember the rule:

$(+x)\times(-x)=-x$

Therefore, the sign of the exercise result will be negative:

$-16\times+1=-16$

Let's recall the law:

$(+x)\times(-x)=-x$

Therefore, the sign of the exercise result will be negative:

$-7\times+1=-7$

Let's remember the rule:

$(-x)\times(-x)=+x$

Therefore, the sign of the exercise result will be positive:

$-10\times-1=+10$

Let's remember the rule:

$(+x)\times(+x)=+x$

Therefore, the sign of the exercise result will be positive:

$+2\times+1=+2$

Let's recall the law:

$(+x)\times(-x)=-x$

Therefore, the sign of the exercise result will be negative:

$-2\times+1=-2$

Let's recall the rule:

$(-x)\times(-x)=+x$

Therefore, the sign of the exercise result will be positive:

$-3\times-1=+3$

Let's remember the rule:

$(+x)\times(-x)=-x$

Therefore, the sign of the exercise result will be negative:

$+1\times-1=-1$

Let's recall the law:

$(+x)\times(-x)=-x$

Therefore, the sign of the exercise result will be negative:

$-1\times+3=-3$

Let's recall the rule:

$(-x)\times(-x)=+x$

Therefore, the sign of the exercise result will be positive:

$-4\times-1=+4$

Let's recall the law:

$(+x)\times(+x)=+x$

Therefore, the sign of the exercise result will be positive:

$+6\times+1=+6$
