What is 700 - 60? A Simple Subtraction Problem

The question "What is 700 - 60?" is a basic subtraction problem. Let's break down how to solve it and explore different methods.

Understanding Subtraction

Subtraction is one of the four fundamental arithmetic operations. It involves finding the difference between two numbers. In this case, we're finding the difference between 700 and 60.

Method 1: Standard Subtraction

The most straightforward method involves aligning the numbers vertically and subtracting column by column, starting from the right:

  700
-  60
-----
  640

• Hundreds column: 7 - 0 = 7
• Tens column: 0 - 6 = -6. Since we can't subtract a larger number from a smaller one, we borrow from the hundreds column. The 7 in the hundreds column becomes a 6, and we add 10 to the 0 in the tens column, making it 10. Now we have 10 - 6 = 4.
• Ones column: 0 - 0 = 0

Therefore, 700 - 60 = 640.

Method 2: Mental Math

For this specific problem, mental math is also quite efficient:

Think of 700 as 600 + 100. Then subtract 60 from 100, which leaves 40. Add that 40 back to the 600 to get 640.

Why is understanding subtraction important?

Subtraction is a crucial skill in everyday life, used in various contexts, including:

• Finance: Calculating remaining balances, tracking expenses, and determining profit margins.
• Measurement: Finding the difference between lengths, weights, or volumes.
• Time: Calculating durations and time differences.
• Problem-solving: Many real-world problems involve finding the difference between two quantities.

Conclusion

The answer to "What is 700 - 60?" is $\boxed{640}$. Understanding subtraction is a fundamental mathematical skill with widespread applications. Whether you use the standard method or mental math, the key is to grasp the concept of finding the difference between two numbers.
