What is -3 + 4?

When adding -3 and 4, start from -3 on the number line and move right by 4 units. Each move to the right increases the value by 1. After moving four steps, you reach 1, which is the answer. Mathematically, adding a negative and positive number involves subtracting the smaller absolute value from the larger and applying the sign of the larger number. Here, the absolute difference is 1, and the larger absolute value is positive, resulting in 1. So, -3 + 4 = 1.
