To tackle these questions, let’s dig into some intriguing facts!
Did you know that the concept of negative numbers dates back to ancient times? The earliest known use of negative numbers was in China around 300 AD, where they were used for bookkeeping. Can you imagine people balancing their accounts with negative figures long before calculators existed? It’s fascinating how mathematics has evolved!
Now, let’s apply this to our real-life scenarios. When you think about directions, representing east as positive integers and west as negative helps simplify navigation. For Rita, after moving 20 km east (positive) and then 30 km west (negative), you would mathematically represent her final position relative to point A as -10 km (20 - 30). So, not only are you learning math, but you’re essentially mastering the art of navigation as well!
