Explanation:

Let's solve question 2 as an example (we can solve others similarly by finding the difference between start, middle, and end to determine the subtraction amount):

Step1: Find the difference between start and middle (or middle and end) to determine the subtraction.

Start is 5462, Middle Result (from example pattern, let's check the end: 4452. Wait, example step one: 5462 -10 = 5452 (middle), step two: 5452 -1 = 5451? Wait, no, the example's step two end is 5451? Wait, the user's image: example start 5462, step one -10 → middle 5452, step two -1 → 5451. Then question 2: start 5462, end is 4452. Let's see the difference between 5462 and 4452: 5462 - 4452 = 1010. But we can only subtract -1, -10, -100, -1000. So possible steps: first subtract 1000 (5462 -1000 = 4462), then subtract 10 (4462 -10 = 4452). Wait, but let's check the middle result. Wait, maybe step one: -1000, step two: -10. Let's verify: 5462 -1000 = 4462 (middle), then 4462 -10 = 4452 (end). Alternatively, maybe step one: -10, step two: -1000? Wait, 5462 -10 = 5452 (middle), 5452 -1000 = 4452 (end). Yes, that works. Let's check the example: step one -10, step two -1. So for question 2, start 5462, step one: -10 → middle 5452, step two: -1000 → 4452. Wait, but the middle result column is empty. Wait, maybe the middle result is after step one, and end after step two. So step one: 5462 -10 = 5452 (middle), step two: 5452 -1000 = 4452 (end). So:

Step1: Subtract 10 from start.

$5462 - 10 = 5452$ (Middle Result)

Step2: Subtract 1000 from middle result.

$5452 - 1000 = 4452$ (End Result)

Answer:

Step One: $-10$, Middle Result: $5452$; Step Two: $-1000$, End Result: $4452$ (for question 2. Other questions can be solved similarly by finding the difference and decomposing into -1, -10, -100, -1000 subtractions).
