Given: (\frac{9}{2} -1)-8

We have to solve the above equation.

By using the Bodmas rule, we are solving the above equation.

As we know that the Bodmas rule is used to remember the order of operations to be followed while solving expressions in mathematics.

Where,

\begin{array}{l}\mathrm{B}=\text{brackets}\\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}

We are solving in the following way:

We have,

(\frac{9}{2} -1)-8

\Rightarrow (\frac{9-2}{2} )-8\\\\\Rightarrow \frac{7}{2} -8\\\\\Rightarrow \frac{7-16}{2} \\\\\Rightarrow \frac{-9}{2}

Hence, the solution of the equation is-9/2 \ or \-4.5.

In accordance with the information provided in the question,

We have found the value of the supplied expression in the above question.

Given in the question (9 by 2-1)-8

Here, we will use BODMAS RULE.  

BODMAS RULE:- It is a correct order to solve the mathematical expression.

Where, B stands for bracket

O stands for of

D stands for divide

M stands for multiplication

A stands for addition

S stands for subtraction.

\Rightarrow (9\div2-1)-8\\\Rightarrow (\frac{9}{2} -1)-8\\\Rightarrow (4.5-1)-8\\\Rightarrow 3.5-8\\=-4.5

Hence the final answer will be -4.5
