Question

15:5X2+4 = 18Where’s the parentheses go to make this correct?

Answer 1

`10^2/5\cdot3+7=200`

For the calculation on the right to have the given result, you have to put the addition on parentheses:

`\begin{gathered} 10^2/5\cdot(3+7) \\ 100/5\cdot10 \\ 20\cdot10 \\ 200 \end{gathered}`

*-*

Same as before, for this equation to be true, you have to put the addition between parentheses:

`15/5\cdot2+4=18`
`\begin{gathered} 15/5\cdot(2+4) \\ 3\cdot6 \\ 18 \end{gathered}`
