Exercise #5

+8:0= +8:0=

Video Solution

Step-by-Step Solution

Let's write the expression in the form of a simple fraction:

80= \frac{8}{0}=

Let's remember the rule:

x0 \frac{x}{0}

It is not possible to divide a number by 0, therefore the expression has no meaning.

Answer

There is no meaning to the expression

Exercise #6

+905:0= +905:0= ?

Video Solution

Step-by-Step Solution

Let's write the expression in the form of a simple fraction:

9050= \frac{-905}{0}=

Remember the rule:

x0 \frac{x}{0}

It is not possible to divide a number by 0, therefore the expression has no meaning.

Answer

There is no meaning to the expression.
