00:00:01.500 --> 00:00:08.470
Natalie was checking her bank account and found her current balance to be negative 460 dollars.
00:00:09.240 --> 00:00:12.440
She deposited 438 dollars.
00:00:13.300 --> 00:00:16.220
What is Natalie’s new account balance?
00:00:17.830 --> 00:00:26.760
We are told that Natalie’s balance was negative 460 dollars, and then she deposited 438 dollars.
00:00:27.870 --> 00:00:35.780
In order to calculate her new balance, we need to add 438 to negative 460.
00:00:37.040 --> 00:00:43.570
In order to solve this calculation, let’s consider a number line from negative 500 to zero.
00:00:44.530 --> 00:00:49.180
We know that Natalie’s balance started at negative 460.
00:00:50.170 --> 00:00:53.970
Adding 400 to this takes us to negative 60.
00:00:54.960 --> 00:00:58.090
We need to add another 38 dollars.
00:00:58.940 --> 00:01:04.070
Negative 60 plus 38 is equal to negative 22.
00:01:05.030 --> 00:01:11.360
We can therefore conclude that Natalie’s new account balance is negative 22 dollars.
