Question

Find the sum of .

a) –30
b) –40
c) –36
d) –24

Answer 1

The sum of the given values is
`\( \text{–}130 \).`

Step-by-step explanation:

To find the sum of the provided values, we add them together:
`\( \text{–}30 + \text{–}40 + \text{–}36 + \text{–}24 \)`. Grouping like terms, we get
`\( \text{–}(30 + 40 + 36 + 24) \)`. Calculating the sum inside the parentheses, we find
`\( \text{–}130 \),` which is the final answer.

Understanding the concept of adding and subtracting integers is fundamental in obtaining the correct result. The negative signs indicate subtraction, and the numerical values represent the magnitudes of the quantities involved. In this case, the negative sum
`\( \text{–}130 \)` signifies that the overall result is a deficit or a decrease from zero.

In conclusion, mathematical operations involving integers require careful attention to signs and the arithmetic rules governing them. The sum of the provided values reflects the combined effect of the negative quantities, resulting in a negative total. This approach aligns with the principles of basic arithmetic and helps in solving problems that involve the manipulation of integers.
