BEDMAS

if i have the numbers -6 5 4 2 and have to use bedmas and use all of the numbers once to get to -10 ?

$\begin{array}{|rcll|} \hline -10 &=& [5-6-4] \cdot 2 \\ -10 &=& \frac{-6-4}{2}-5 \\ \hline \end{array}$

and a seperate question same instructions -22 how do i do it?

$\begin{array}{|rcll|} \hline -22 &=& (5-2)\cdot (-6)-4 \\ -22 &=& \frac{(-6-5)\cdot4}{2} \\ \hline \end{array}$

[-6 - 2 ] * 5   / 4  =

[ - 8 ] * 5   / 4   =

- 40  / 4   =

-10

-6 * 5  +  4 * 2  =

-30 + 8  =

-22
