So first, subtract the original number, which is 2, with the second number, which is 1.6. After you finish Subtracting 2 - 1.6, divide our answer by 2, the original number. So pretty much our problem so far looks like this |dw:1442328032710:dw|
so you will get 12
I'm sorry, subtract 1.6 - 2, not 2 - 1.6|dw:1442328137383:dw|
so it 2
Not quite. 1.6 - 2 will be a negative decimal
Right, so now we have |dw:1442328255258:dw|
What do you get? This will also be a negative decimal
