1234 + 607
To solve these addition and subtraction problems, you can use the columnar addition and subtraction method.
For addition:
1234 + 607:
Start by aligning the numbers vertically, with the ones digit (4 and 7) on the right side.
1234
+ 607
------
Add the ones digit: 4 + 7 = 11. Write down the ones digit 1 and carry over the tens digit 1.
1234
+ 607
------
1
Then, add the tens digit: 3 + 0 (from 607) + 1 (carried over) = 4.
1234
+ 607
------
14
Finally, add the hundreds digit: 2 + 6 = 8.
1234
+ 607
------
841
So, 1234 + 607 = 841.
Now, let's move on to the second addition problem:
47,019 + 21,598:
47,019
+ 21,598
---------
Add the ones digit: 9 + 8 = 17. Write down the ones digit 7 and carry over the tens digit 1.
47,019
+ 21,598
---------
7
Add the tens digit: 1 (carried over) + 1 + 9 = 11. Write down the ones digit 1 and carry over the hundreds digit 1.
47,019
+ 21,598
---------
17
Add the hundreds digit: 1 (carried over) + 5 + 0 = 6.
47,019
+ 21,598
---------
617
Add the thousands digit: 1 + 2 + 4 = 7.
47,019
+ 21,598
---------
7,617
So, 47,019 + 21,598 = 7,617.
Now, let's move on to the third addition problem:
405,679 + 319,477:
405,679
+ 319,477
----------
Add the ones digit: 9 + 7 = 16. Write down the ones digit 6 and carry over the tens digit 1.
405,679
+ 319,477
----------
6
Add the tens digit: 1 (carried over) + 7 + 7 = 15. Write down the ones digit 5 and carry over the hundreds digit 1.
405,679
+ 319,477
----------
56
Add the hundreds digit: 1 (carried over) + 6 + 4 = 11. Write down the ones digit 1 and carry over the thousands digit 1.
405,679
+ 319,477
----------
156
Add the thousands digit: 1 (carried over) + 5 + 9 = 15. Write down the ones digit 5 and carry over the ten thousands digit 1.
405,679
+ 319,477
----------
5156
Add the ten thousands digit: 1 (carried over) + 0 + 3 = 4.
405,679
+ 319,477
----------
4,156
So, 405,679 + 319,477 = 4,156.
Now, let's move on to the subtraction problems using the same method:
1234 - 607:
Start by aligning the numbers vertically, with the ones digit (4 and 7) on the right side.
1234
- 607
------
Subtract the ones digit: 4 - 7. Since 4 is smaller than 7, we need to borrow.
From the tens digit, borrow 1, making it 3. This also changes the hundreds digit to 11.
Now, subtract: 14 - 7 = 7.
1234
- 607
------
7
So, 1234 - 607 = 7.
Now, let's move on to the second subtraction problem:
47,019 - 21,598:
47,019
- 21,598
---------
Subtract the ones digit: 9 - 8 = 1.
47,019
- 21,598
---------
1
Subtract the tens digit: 1 (borrowed in ones digit) - 9 = -8.
Since we have a negative result, we need to borrow from the hundreds digit.
This changes the hundreds digit to 0 and the thousands digit to 6.
Now, subtract: 16 - 9 = 7.
47,019
- 21,598
---------
71
So, 47,019 - 21,598 = 71.
Now, let's move on to the third subtraction problem:
405,679 - 319,477:
405,679
- 319,477
---------
Subtract the ones digit: 9 - 7 = 2.
405,679
- 319,477
---------
2
Subtract the tens digit: 7 - 7 = 0.
405,679
- 319,477
---------
02
Subtract the hundreds digit: 6 - 4 = 2.
405,679
- 319,477
---------
202
Subtract the thousands digit: 5 - 1 = 4.
405,679
- 319,477
---------
4202
Subtract the ten thousands digit: 4 - 3 = 1.
405,679
- 319,477
---------
14202
So, 405,679 - 319,477 = 14,202.
