Order of Operations, It Matters!

We are learning about Order of Operations! Order matters if you want the right answer!  For example: IF you solve in order from left to right you get this answer:   $10 - 2 x $4  = $32   That would mean that you walked into a store with $10, bought 2 items for $4, and left with $32! NO! 

 $10 - (2 x $4)  = ? 

$10 - $8 = $2
You walked into a store with $10. You bought 2 items costing $4 each. You left with $2. 

YES!
