Natalie was checking her bank account and found her current balance to be negative 460 dollars. She deposited 438 dollars. What is Natalie’s new account balance?
We are told that Natalie’s balance was negative 460 dollars, and then she deposited 438 dollars. In order to calculate her new balance, we need to add 438 to negative 460. In order to solve this calculation, let’s consider a number line from negative 500 to zero. We know that Natalie’s balance started at negative 460. Adding 400 to this takes us to negative 60. We need to add another 38 dollars. Negative 60 plus 38 is equal to negative 22. We can therefore conclude that Natalie’s new account balance is negative 22 dollars.
