Happy Monday! I hope you are well-rested! Today's Math Monday blog prompt is to explain what negative numbers are and give an example of where we might find them in the real world.
There are a lot of ways to explain what negative numbers are, I guess, but most people know them as being the opposites of positive numbers, or ones whose values are above zero. This makes them integers along with their opposites. Being the opposite of a number means that the absolute value as the same as its counterpart, but the sign is different. For example, -8 has the same value as 8, or +8, but the signs are different. One of them is negative and you read it as "negative eight".
Negative numbers are taught to us pretty early on because they are fairly simple to use and are more applicable to the real world than some other concepts. If you owe anyone money measured in value, then you say that you have -x dollars, unless you have more to make up for it. Adding a negative number to a value is the same as subtracting its opposite. You can do this lots of times in lots of ways. If you have a discount at a store, for example, and you find out what the rate of discount is in a number, you can add the negative value to the original price. For example, if an item was originally $30 dollars but is on sale, or discount, for 10%, you can add -3 to 30. This is the same as carrying out the equation 30-3. The item now costs $27. Easy, right?
We began learning about negative numbers in the recent years past, but they've come into play a lot in this year's math class, and we've been told before that they'll definitely be on tomorrow's CST for mathematics. Not only are they applicable in the real world, but they can also be used within the field of mathematics too. We've used them in a lot of other units this year. They really are one of the basics of math we've learned about.
