Answer:
To evaluate the expression -1 + 1 / -1, we follow the order of operations, which is commonly remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
1. Division: In this expression, the division operation comes before addition. So, we start by evaluating 1 / -1.
1 divided by -1 is equal to -1.
So, the expression becomes -1 + (-1).
2. Addition: Now, we can simplify the expression by performing the addition operation.
-1 + (-1) is equal to -2.
Therefore, the value of -1 + 1 / -1 is -2.
