I'll be glad to check your answer.
To solve the expression -9 - (-1), we need to follow the order of operations, also known as the PEMDAS rule. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break it down step by step:
Step 1: Simplify the expression inside the parentheses.
-9 - (-1)
Since we have a negative sign before the second parentheses, we need to change the signs of all terms inside the parentheses.
-9 + 1
Step 2: Perform the addition/subtraction.
-9 + 1 = -8
So, -9 - (-1) simplifies to -8.
Explanation:
To solve this expression, you need to understand the concept of subtracting a negative number. When we subtract a negative number, it is equivalent to adding its positive counterpart. In this case, -(-1) becomes +1. Hence, we end up with -9 + 1, which equals -8.
