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

Complete the following exercise:

$1\cdot(-1)=$

Let's remember the rule:

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

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

$+1\times-1=-1$

$-1$

Complete the following exercise:

$10\cdot(-1)=$

Let's recall the rule:

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

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

$+10\times-1=-10$

$-10$

Solve the following exercise:

$(-10)\cdot2=$

Let's recall the rule:

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

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

$-10\times+2=-20$

$-20$

Complete the following exercise:

$(-8)\cdot3=$

Let's remember the rule:

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

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

$-8\times+3=-24$

$-24$

Complete the following exercise:

$(-6)\cdot2=$

Let's recall the rule:

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

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

$-6\times+2=-12$

$-12$

Complete the following exercise:

$(-1)\cdot4=$

Let's remember the rule:

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

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

$-1\times+4=-4$

$-4$

Complete the following exercise:

$30\cdot(-2)=$

Let's recall the law:

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

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

$+30\times-2=-60$

$-60$

Complete the following exercise:

$2\cdot(-7)=$

Let's recall the rule:

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

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

$+2\times-7=-14$

$-14$

Complete the following exercise:

$3\cdot(-4)=$

Let's remember the rule:

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

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

$+3\times-4=-12$

$-12$

Complete the following exercise:

$2\cdot(-4)=$

Let's recall the rule:

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

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

$+2\times-4=-8$

$-8$
