Multiplication and Division of Signed Mumbers: Multiplication of signed numbers

$200:-200\cdot200=$

Let's solve the exercise from left to right.

First, we'll write the division problem in the form of a fraction:

$\frac{200}{-200}\times200=$

We should note that we are dividing a positive number by a negative number, so the result will necessarily be a negative number:

$-\frac{200}{200}\times200=$

Let's simplify the 200 and we get:

$-200$

$-200$

$-3\cdot8:0\cdot-14=$

Let's write the exercise in the following way:

$\frac{-3\times8}{0}\times-14=$

We'll remember that it's not possible to divide a number by zero, and therefore the expression has no meaning.

There is no meaning to the expression

$38:(-4)\cdot12:(-3)=$

$38$

$-13\cdot4:-8=$

$6\frac{1}{2}$

$-5\cdot-49:14\cdot-10=$

$-175$

$-81:-27\cdot6:-2=$

$-9$

$-49:-7\cdot3\cdot-\frac{1}{4}=$

$-5\frac{1}{4}$

$+400\cdot(-4):-16:-6=$

$-16\frac{2}{3}$
