Part 2: Find the answer
Here are the step-by-step calculations for the addition and subtraction problems.
1. $85,674 + 14,312$
* Ones: $4 + 2 = 6$
* Tens: $7 + 1 = 8$
* Hundreds: $6 + 3 = 9$
* Thousands: $5 + 4 = 9$
* Ten Thousands: $8 + 1 = 9$
*
Answer: $99,986$
2. $47,546 - 16,420$
* Ones: $6 - 0 = 6$
* Tens: $4 - 2 = 2$
* Hundreds: $5 - 4 = 1$
* Thousands: $7 - 6 = 1$
* Ten Thousands: $4 - 1 = 3$
*
Answer: $31,126$
3. $16,234 + 72,323$
* Ones: $4 + 3 = 7$
* Tens: $3 + 2 = 5$
* Hundreds: $2 + 3 = 5$
* Thousands: $6 + 2 = 8$
* Ten Thousands: $1 + 7 = 8$
*
Answer: $88,557$
4. $56,318 + 14,194$
* Ones: $8 + 4 = 12$ (Write 2, carry over 1)
* Tens: $1 + 9 + 1 \text{ (carry)} = 11$ (Write 1, carry over 1)
* Hundreds: $3 + 1 + 1 \text{ (carry)} = 5$
* Thousands: $6 + 4 = 10$ (Write 0, carry over 1)
* Ten Thousands: $5 + 1 + 1 \text{ (carry)} = 7$
*
Answer: $70,512$
*(The red boxes at the top represent the carried numbers: 1, 1, and 1)*
5. $57,462 - 11,307$
* Ones: $2 - 7$ (Need to borrow). Borrow from tens. $12 - 7 = 5$.
* Tens: The 6 became a 5. $5 - 0 = 5$.
* Hundreds: $4 - 3 = 1$.
* Thousands: $7 - 1 = 6$.
* Ten Thousands: $5 - 1 = 4$.
*
Answer: $46,155$
*(The red boxes at the top represent the borrowing marks)*
6. $25,827 + 72,113$
* Ones: $7 + 3 = 10$ (Write 0, carry over 1)
* Tens: $2 + 1 + 1 \text{ (carry)} = 4$
* Hundreds: $8 + 1 = 9$
* Thousands: $5 + 2 = 7$
* Ten Thousands: $2 + 7 = 9$
*
Answer: $97,940$
*(The red box at the top represents the carried number: 1)*
