Perform the indicated operations and simplify: ( − 6 8 ) − ( − 4 )

To determine

To calculate: The simplified form of the expression (68)(4) by performing the indicated operation.

Explanation

Given Information:

The provided expression is (68)(4).

Formula used:

Equivalent signed fractions:

ab=ab=ab

The equivalent signed fraction shows that a negative fraction can be written in three different but equivalent forms.

Where,

ab is the customary form.

And,

Subtracting two signed numbers includes:

1. In order to subtract two signed numbers, the sign of the number being subtracted must be changed.

2. And then added to the other number in accordance with the rules for addition of signed numbers

Calculation:

Consider the expression:

(68)(4)

Rewrite (4) as (41) in the above expression.

(68)(4)=(68)(41)

Change the given expression to customary form. That is,

(68)(41)=(68)(41)

Now, in order to subtract two signed numbers, the sign of the number being subtracted must be changed and then added in accordance with the rules for addition of signed numbers. That is,

(68)(41)=(68)+(+41)

When fractions having different denominator are to be added; first step is to find the least common denominator (LCD)
