What are given numbers called during addition? 2. What is the value after summation of numbers called? 3. What are given numbers called during differentiation? 4. What is the value after differentiation of numbers called? 5. What is differentiation and by what action is it tested? 6. From which side the calculation of written addition starts? What about verbal calculation? -7. When comparing five-digital numbers, which categories are compared first and which second? 8. What number is obtained after subtracting the smallest five- digital numbers from largest five-digital number? 9. Subtract the largest four-digital numbers from the smallest five-digital number.

Sure! Here are the answers to your questions: 1. **Given numbers during addition** are called **addends**. 2. **The value after summation of numbers** is called the **sum**. 3. **Given numbers during differentiation** are referred to as the **functions** or **variables** being differentiated. 4. **The value after differentiation** of numbers is called the **derivative**. 5. **Differentiation** is a mathematical process that finds the rate at which a function is changing at any given point. It is typically tested by calculating limits, checking whether the derivative exists using the definition, or using rules of differentiation. 6. **In written addition**, the calculation starts from the **right side** (the least significant digit) and moves to the left. For **verbal calculation**, it may vary based on how the person processes the information, but typically it's the same process. 7. When comparing **five-digit numbers**, the **most significant digit** (the leftmost digit) is compared first (thousands place), followed by the **next most significant digit** if the first is equal, and so forth until all digits are compared. 8. To find the number obtained after subtracting the smallest five-digit number (10000) from the largest five-digit number (99999), you perform the operation: 99999 - 10000 = 89999. 9. To subtract the largest four-digit number (9999) from the smallest five-digit number (10000), you calculate: 10000 - 9999 = 1. Let me know if you need further assistance!
