Understanding Negative Number Addition

Adding two negative numbers is similar to moving further to the left on a number line. Imagine you are at 0, and you move 5 steps to the left (representing -5). Then, you move another 3 steps to the left (representing -3). In total, you have moved 8 steps to the left from 0, which is -8.

Formula: When adding two negative numbers, say -a and -b, the sum is always -(a + b). For example, -5 + (-3) = -(5 + 3) = -8.

This tool helps you quickly calculate and visualize the sum of any two negative numbers. Feel free to experiment with different values and enhance your understanding of negative number arithmetic!
