$\displaystyle\huge\red{\underline{\underline{Solution}}}$

TO DETERMINE

The comparison between

$\displaystyle \sf{ - \frac{7}{2} + 0} \: \: \: and \: \: 0 + \bigg[ - \frac{7}{2} \: \bigg ]$

EVALUATION

Here 0 is a Additive Identity for the set of Real numbers

So by the property of Real numbers

$\displaystyle \sf{ - \frac{7}{2} + 0} \: \: \: = \: - \frac{7}{2}$

Now

[ x ] is the greatest integer but not greater than x

This function is called Box function

So

$\displaystyle \sf{\bigg[ - \frac{7}{2} \: \bigg ] = \bigg[ - 3.5 \: \bigg ] = - 4\: }$

Therefore

$\displaystyle \sf{ 0 + \bigg[ - \frac{7}{2} \: \bigg ] = 0 - 4 = - 4 }$
