Explanation:

Problem 1: \( 370 - 255 \)

Step 1: Subtract ones place

\( 0 - 5 \) is not possible, so we regroup. Borrow 1 from the tens place. The 7 in the tens place becomes 6, and the 0 in the ones place becomes 10. Now, \( 10 - 5 = 5 \).

Step 2: Subtract tens place

We have 6 (after regrouping) in the tens place. \( 6 - 5 = 1 \).

Step 3: Subtract hundreds place

\( 3 - 2 = 1 \).

Step 1: Subtract ones place

\( 2 - 9 \) is not possible, so we regroup. Borrow 1 from the tens place. The 8 in the tens place becomes 7, and the 2 in the ones place becomes 12. Now, \( 12 - 9 = 3 \).

Step 2: Subtract tens place

We have 7 (after regrouping) in the tens place. \( 7 - 0 = 7 \).

Step 3: Subtract hundreds place

\( 3 - 2 = 1 \).

Step 1: Subtract ones place

\( 5 - 8 \) is not possible, so we regroup. Borrow 1 from the tens place. The 9 in the tens place becomes 8, and the 5 in the ones place becomes 15. Now, \( 15 - 8 = 7 \).

Step 2: Subtract tens place

We have 8 (after regrouping) in the tens place. \( 8 - 6 = 2 \).

Step 3: Subtract hundreds place

\( 4 - 1 = 3 \).

Answer:

\( 115 \)

Problem 2: \( 382 - 209 \)
