The final result is $-117.1$.
Steps to Solve
- Identify the values to add
We have two negative numbers: $-45.3$ and $-71.8$.
- Add the absolute values
To add two negative numbers, we first add their absolute values: $$ |-45.3| + |-71.8| = 45.3 + 71.8 $$
- Calculate the sum of absolute values
Now, perform the addition: $$ 45.3 + 71.8 = 117.1 $$
- Apply the negative sign
Since both numbers are negative, the result will also be negative: $$ -45.3 + (-71.8) = -117.1 $$
The final result is $-117.1$.
More Information
When adding negative numbers, the result is always negative, and the sum is equal to the sum of their absolute values, with a negative sign applied.
Tips
- Forgetting to add the absolute values before applying the negative sign.
- Confusing addition of negative numbers with subtraction.
