Steps to Solve
- Identify the numbers to add
The problem involves adding two numbers: $12.54$ (a positive number) and $-24.673$ (a negative number).
- Rewrite the addition operation
When adding a positive number to a negative number, you can think of it as subtraction. Thus, the operation can be rewritten as: $$ 12.54 + (-24.673) = 12.54 - 24.673 $$
- Perform the subtraction
Now, let's perform the subtraction: $$ 12.54 - 24.673 $$
Since $24.673$ is larger than $12.54$, the result will be negative.
- Calculate the absolute values and combine
Calculate: $$ 24.673 - 12.54 = 12.133 $$
Since the larger absolute value is from the negative number, the final answer will be: $$ -12.133 $$
The final answer is $-12.133$.
More Information
When adding a positive number and a negative number, the result depends on which number has the larger absolute value. In this case, the negative number was larger, leading to a negative result.
Tips
