Question

Use brackets to make the following statement correct. 15 - 2 x 3 + 4 + 2 = 2.5

Answer 1

Let's add parenthesis inside the expression to make it true

`\begin{gathered} (15-(2*3+4))/2=2.5 \\ \end{gathered}`

Let's solve the expression to check

`\begin{gathered} (15-(2*3+4))/2 \\ (15-(6+4))/2 \\ (15-10)/2 \\ 5/2 \\ 2.5 \end{gathered}`
