Study Notes

Basic Arithmetic Operations

Subtraction of integers can yield negative results: 8 - 79 equals -71.
Adding two negative integers results in a more negative integer: -19 + (-17) equals -36.
Combining a positive integer with a negative integer can decrease the overall value: 39 + (-6) equals 33.

Handling Negative Numbers

Adding a negative integer to a more significant negative integer will lower the total: -543 + 217 equals -326.
Subtracting a larger positive integer from a smaller one gives a negative result: 14 + (-42) equals -28.
The result of subtracting a larger positive integer from a smaller one: 11 - 46 equals -35.

Evaluation of Expressions with Variables

In expressions with variables, substituting values is necessary for evaluation.
For a = -312 and b = 405, calculating -a + -b gives 312 + 405, resulting in 717.
For x = 7 and y = -31, evaluating -x - y leads to -7 + 31, which equals 24.

Absolute Values and Their Calculations

The absolute value represents the non-negative magnitude: |47 + (-58)| calculates to |-11|, ultimately equaling 11.
Subtraction involving absolute values can lead to conflicts or refinements: computing -17 - (-62) equals -17 + 62, resulting in 45.
