What is -5 + 7?

When you add -5 and 7, the calculation involves moving along a number line from -5 and then going 7 units in the positive direction. Moving from -5 up by 7 cancels out the 5 negative units and adds 2 more in the positive direction, which brings the final result to 2. This is why the answer is 2, as each positive step reduces the negative number toward zero and then shifts it into positive territory. Therefore, -5 + 7 results in a net movement of 2 units to the right, which is positive 2.
