Find the sum. $$-11.6+6.4+(-3.0)$$

Short answer

The sum of \(-11.6+6.4+(-3.0)\) is \(-8.2\)

Step-by-step solution

Addition of positive and negative numbers

Firstly, separate the positive and negative numbers. We have \(-11.6\) and \(-3.0\) as negative numbers, and \(6.4\) as positive number.

Add negative numbers together

When we add the negative numbers, \(-11.6 + -3.0\) we get \(-14.6\)

Add result from Step 2 to the positive number

Afterwards, we add the sum of the negative numbers from step 2 to the positive number, \(-14.6 + 6.4\). The answer is \(-8.2\).
