Step-by-step explanation:
The student's question involves evaluating the expression (3×75)−55+3.
To solve this, we should follow the order of operations, commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
In this expression, we first perform the multiplication within parentheses, then subtraction, and lastly, addition.
Let's break this down step-by-step:
- Multiply 3 by 75 to get 225.
- Subtract 55 from the result of the first step to get 170.
- Lastly, add 3 to the result of the second step to arrive at the final answer, which is 173.
Therefore, the expression simplifies to 173.
