Multiplication of Integers

Verify the following:
$(-23)\left\{\right(-5)+(+19\left)\right\}=(-23)\times (-5)+(-23)\times (+19)$

Verify the following:
$19\times \{7+(-3\left)\right\}=19\times 7+19\times (-3)$
 

What must be subtracted from $- 6$ to obtain $-14 ?$

The sum of two integers is $24 .$ If one of them is $-19 ,$ then the other is

By how much less than $-3$is $-7?$

By how much does $5$ exceed $-4?$

The modulus of an integer $x$ is $9,$ then

The additive inverse of $-7$ is

$(-1)+(-1)+(-1)+(-1)+\_\_\_\_\_500$ times$=$

$(-1)\times (-1)\times (-1)\times (-1)\times \_\_\_\_\_500$ times $=$

There does not exist an integer $b$ such that for $a>1,a\times b=b\times a=b$

 The product of a negative and a positive integer may be zero.
 

 For all non-zero integers $a$ and $b,a\times b$ is always greater than either $a$ or $b$.

Of the two integers, if one is negative, then their product must be positive.

The product of three negative integers is a negative integer.

The product of a positive and a negative integer is negative.
 

If $a\times (-1)=30,$ is the integer $a$ positive or negative?

If $a\times (-1)=-30,$ is the integer $a$ positive or negative?

State which is greater:
$(8+9)\times 10$ and $8+9\times 10$
 

State which is greater:
$(8-9)\times 10$ and $8-9\times 10$
