Final answer:
The equation is a subtraction problem where a larger number is being subtracted from a smaller number resulting in a negative answer. The correct answer to the problem 400 - 500 is -100.
Step-by-step explanation:
The student's equation, 400 - 500 = 600.0059, is incorrect. It seems like there might be some confusion about subtraction. In maths, if you subtract a larger number from a smaller one, you would get a negative number. Hence, 400 - 500 should equal to -100, not 600.0059. Let's break it down:
- Start with the number 400.
- Subtract 500 from 400.
- Because 500 is larger than 400, the result will be a negative number.
- The difference between the two numbers is 100, therefore, the result is -100.
So, the correct answer to 400 - 500 is -100.
