7 - 4,099 - 500

Explanation:

Problem 2:

Step1: Add units place

$6 + 4 = 10$, carry over 1 to tens place.

Step2: Add tens place

$3 + 6 + 1 = 10$, carry over 1 to hundreds place.

Step3: Add hundreds place

$5 + 5 + 1 = 11$.

Step1: Add hundreds place

$4 + 5 = 9$, tens and units are 0.

Step1: Subtract units place

$5 - 9$ not possible, borrow 1 from tens place (tens is 0, so borrow from hundreds, then tens, then units). Units become $15 - 9 = 6$.

Step2: Subtract tens place

After borrowing, tens is $9 - 9 = 0$.

Step3: Subtract hundreds place

After borrowing, hundreds is $9 - 0 = 9$.

Step4: Subtract thousands place

$5 - 1 - 4 = 0$ (after previous borrows).

Answer:

$1100$
