Answer 1

To simplify the expression 4 - 3 + _____, perform the subtraction first and then the addition. The answer cannot be determined without knowing the missing value.

Step-by-step explanation:

To simplify the expression 4 - 3 + ____, we can use the order of operations, also known as PEMDAS. This stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). First, we perform the subtraction, 4 - 3, which gives us 1. Then, we perform the addition, 1 + _____. Since the expression is missing a term, we cannot simplify it any further without knowing the missing value. Therefore, the answer is not among the given options A) 0, B) 1, C) 4, D) -1, or E) 7.
