Question

Write out step by step what needs to be done in order to get the answer to the expression bel

Answer 1

Let's begin by listing out the given information:

`2^3\cdot5-4/2`

We will calcuate using the BODMAS (Bracket Of Division, Multiplication, Addition, Subtraction) operation

`\begin{gathered} 2^3\cdot5-4/2 \\ \text{There is no bracket here. We proceed to take care of the ''D (division)''} \\ \Rightarrow4/2=2 \\ \\ 2^3\cdot5-4/2\Rightarrow2^3\cdot5-2 \\ 2^3\cdot5-2 \\ We\text{ proceed to take care of the ''M (multiplication)''} \\ 2^3\cdot5=2\cdot2\cdot2\cdot5=40 \\ 2^3\cdot5-4/2\Rightarrow40-2 \\ \\ 40-2=38 \\ \\ \therefore2^3\cdot5-4/2=38 \end{gathered}`
