Understanding Negative Numbers

Negative numbers are a fundamental concept in mathematics, and they are used to represent quantities that are less than zero. In the number line, negative numbers are located to the left of zero, while positive numbers are located to the right. The number -10 is a negative number, which means it is 10 units to the left of zero on the number line.

The Concept of Difference

The difference between two numbers is the result of subtracting one number from another. In the case of -10 and 20, we need to find the difference between these two numbers. To do this, we will subtract -10 from 20.

Calculating the Difference

To calculate the difference between -10 and 20, we can use the following steps:

Subtracting a negative number: When we subtract a negative number, we are essentially adding the positive equivalent of that number. In this case, subtracting -10 is equivalent to adding 10.
Performing the subtraction: Now that we have added 10 to 20, we can perform the subtraction. 20 - 10 = 10.

Conclusion

In conclusion, the difference between -10 and 20 is 10. This is because when we subtract a negative number, we are essentially adding the positive equivalent of that number. Understanding the concept of negative numbers and the operation of subtraction is crucial in mathematics, and it's essential to grasp these concepts to perform calculations accurately.
