When adding positive and negative numbers, you simply subtract the absolute values and keep the sign of the larger absolute value. Here, you take the absolute value of 15, which is 15, and the absolute value of -3, which is 3. So, 15 - 3 = 12. Since 15 is positive, the result is positive as well. Therefore, \( 15 + (-3) = 12 \). So, \( \square = 12 \).
