Introduction

Mathematics is a fascinating subject that deals with numbers, quantities, and shapes. It is a fundamental tool used in various fields such as science, engineering, economics, and finance. In this article, we will explore a simple yet intriguing math problem that involves subtraction. Specifically, we will investigate what must be subtracted from -1 to get minus 69.

Understanding the Problem

The problem at hand is a basic subtraction question that requires us to find the difference between two numbers. In this case, we are given the number -1 and asked to find the value that must be subtracted from it to get -69. This problem can be represented mathematically as:

-1 - x = -69

where x is the unknown value that must be subtracted from -1 to get -69.

Solving the Problem

To solve this problem, we need to isolate the variable x by performing algebraic operations on both sides of the equation. We can start by adding x to both sides of the equation to get:

-1 - x + x = -69 + x

This simplifies to:

-1 = -69 + x

Next, we can add 69 to both sides of the equation to get:

-1 + 69 = -69 + 69 + x

This simplifies to:

68 = x

Therefore, the value that must be subtracted from -1 to get -69 is 68.

Explanation and Verification

Let's verify our solution by plugging it back into the original equation:

-1 - 68 = -69

This simplifies to:

-69 = -69

As we can see, our solution is correct. The value of 68 is indeed the correct answer to the problem.

Conclusion

In conclusion, the value that must be subtracted from -1 to get -69 is 68. This problem is a simple yet effective example of how algebraic operations can be used to solve mathematical equations. By following the steps outlined in this article, we can confidently arrive at the correct solution to this problem.
