Solve Integer Addition: (+71) + (-18) Step by Step

To solve this problem, we'll follow these steps:

• Calculate the absolute values of the numbers: $|+71| = 71$ and $|-18| = 18$.
• Subtract the smaller absolute value from the larger one: $71 - 18 = 53$.
• Determine the sign of the result by using the sign of the number with the larger absolute value. Here, $71$ is larger and positive, so the result is positive.

Now, let's go through the calculations:
Step 1: Calculate the absolute difference $71 - 18 = 53$.
Step 2: The number with the larger absolute value is $71$, which is positive. Thus, the result is also positive.

Therefore, the solution to the problem is $53$.
