The final result is $-117.1$.

Steps to Solve

  1. Identify the values to add

We have two negative numbers: $-45.3$ and $-71.8$.

  1. Add the absolute values

To add two negative numbers, we first add their absolute values: $$ |-45.3| + |-71.8| = 45.3 + 71.8 $$

  1. Calculate the sum of absolute values

Now, perform the addition: $$ 45.3 + 71.8 = 117.1 $$

  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.
