The formula for adding two numbers is simple: a + b. However, when dealing with positive and negative numbers, it’s essential to consider the signs. When adding two numbers with the same sign, you add their absolute values. When adding two numbers with different signs, you subtract the smaller absolute value from the larger one.
Real-World Examples
Let’s consider three scenarios:
- Adding two positive numbers: 5 + 3 = 8
- Adding a positive and a negative number (positive is larger): 5 + (-3) = 2
- Adding a positive and a negative number (negative is larger): (-5) + 3 = -2
