To solve the problem of subtracting -6 from -7, you need to understand how subtraction involving negative numbers works. When you subtract a negative number, it is equivalent to adding the positive version of that number.

In this case, if you start with -7 and subtract -6, you can rewrite this as -7 + 6. When you add these two numbers together, the result is calculated as follows:

-7 + 6 = -1

The numbers can be visualized on a number line, where moving to the right indicates adding and moving to the left indicates subtracting. Starting at -7 and moving 6 units to the right takes you to -1.

This concept can often lead to confusion, but it is crucial in arithmetic operations involving negative numbers. Understanding this property helps clarify the answer that -1 is the result of subtracting -6 from -7.
