To solve the addition of two negative decimal numbers [tex]\( (-0.3) + (-0.25) \)[/tex], follow these steps:
1. Understand the Concept of Adding Negative Numbers:
When adding two negative numbers, the sum will also be negative. This is because adding a negative value moves you further left on the number line.
2. Combine the Absolute Values:
- The absolute value of [tex]\( -0.3 \)[/tex] is [tex]\( 0.3 \)[/tex].
- The absolute value of [tex]\( -0.25 \)[/tex] is [tex]\( 0.25 \)[/tex].
Add these absolute values together:
[tex]\[
0.3 + 0.25 = 0.55
\][/tex]
3. Apply the Negative Sign:
Since both original numbers were negative, the sum of their absolute values will also take a negative sign. Hence, the combined number is [tex]\( -0.55 \)[/tex].
4. Write the Final Answer:
[tex]\[
(-0.3) + (-0.25) = -0.55
\][/tex]
So, the result of [tex]\( (-0.3) + (-0.25) \)[/tex] is indeed [tex]\( -0.55 \)[/tex].
