Answer for screen readers
The answer will be the result of the calculation $a + b$.
Steps to Solve
-
Identify the numbers involved
Clearly define the numbers you are working with. Let's say the first number is $a$ and the negative number is $-b$. -
Set up the subtraction
To subtract a negative number from another number, you rewrite the operation. The operation you want to perform is given by:
$$ a - (-b) $$ -
Apply the rule for subtracting negatives
Subtracting a negative is the same as adding the positive. Therefore, you will change the subtraction of a negative number into an addition:
$$ a - (-b) = a + b $$ -
Simplify the expression
Now, simply calculate $a + b$. This will give you the final result.
The answer will be the result of the calculation $a + b$.
More Information
Subtracting a negative number is a common mathematical operation. It is essential to remember that this operation equates to adding the positive version of that number, which can also be helpful in various algebraic contexts and simplifications.
Tips
- One common mistake is forgetting to change the sign when subtracting a negative number. Ensure you remember that $-(-b)$ becomes $+b$ for proper calculations.
