ok here's yet another question...
Suppose the balance in your checking account was $234.15 when you wrote a check for $439.87. (This is known as overdrawing your account.) Describe the account's new balance. [["subtracting real numbers" or "subtracting integers"]]

STOP ALREADY! Ask how to do it or for advice NOT ANSWERS!
As for help with this problem.... think of it in terms of a number line! If you start on a POSITIVE 5 (moving 5 spaces to the right of 0) and take away 7 (move 7 places to the left)... Where do you end up? You will end up at -2 (negative 2 or two spaces to the LEFT of 0)....
Basically... if you are subtracting a larger number from a smaller one... you know that you will end up with a negative number.
So, flip the numbers, add the numbers after placing a negative sign in front of the now first number!
( - 439.87 + 234.15) commutative property of addition (even with negative numbers - it works.)
234.15 - 439.87 = $ - 205.72 (Negative $ 205.72)

$234.15 - $439.87 = -$205.72 Im not sure what they want you to describe other than the fact that you are negative with your balance..
