To add -815 and 415, we start by adding the numbers without considering the signs:
-815 + 415 = -400
Since the signs of the numbers are different, we need to consider the signs of each number.
-815 is negative, and 415 is positive. When adding a positive and a negative number, we subtract the smaller value from the larger value and keep the sign of the larger value.
In this case, the magnitude of -815 is larger than 415, so we subtract 415 from -815 and keep the negative sign.
-815 - 415 = -1230
Therefore, the sum of -815 and 415 is -1230.
To solve the addition problem -815 + 415, you need to add the two numbers together.
