Answer for screen readers
The final answer is $-9$.
Steps to Solve
- Identify the numbers involved
We have two numbers: negative seven, which can be written as $-7$, and positive two written as $2$.
- Set up the subtraction operation
To find the result of subtracting two from negative seven, we can express this as:
$$ -7 - 2 $$
- Perform the subtraction
Now we will perform the subtraction: When subtracting a positive number, it is the same as adding a negative number. Thus, we rewrite our equation as:
$$ -7 + (-2) $$
- Combine the numbers
Now we need to combine the two negative numbers:
$$ -7 + (-2) = -9 $$
The final answer is $-9$.
More Information
Subtracting a positive number from a negative number always results in a larger negative number. In this case, we went further down the number line into the negatives.
Tips
- A common mistake is overlooking the signs when performing operations. Always ensure to carefully consider the signs (positive or negative) of the numbers involved in the calculation.
- Another mistake is misunderstanding that subtracting a positive is equivalent to adding a negative.
