Understanding (-1) + (-5)
Adding negative numbers can sometimes be tricky, but there's a simple way to think about it.
The Concept of Negatives
Imagine a number line. Zero is in the middle. Numbers to the right of zero are positive, and numbers to the left are negative.
Think of adding a negative number as moving to the left on the number line.
Solving (-1) + (-5)
- Start at -1. Mark this point on your imaginary number line.
- Add -5. This means move five spaces to the left from -1.
- You end up at -6.
Therefore, (-1) + (-5) = -6
Key takeaway
When adding two negative numbers, the result will always be a negative number that is larger in magnitude (further away from zero) than either of the original numbers.
