1. Explain why you would use front end estimation. Gie an example of one time you might use it.

2. Explain in words how to add 234+467. Make sure to explain regrouping, if necessary.

Thanks for your help!

2)

234 +
467
** 4+7 = 11
** 60+30= 90
**200+300=600
Answer =600 + 90 +11= 701

1. Front end estimation is a quick and approximate method used to estimate the sum of two numbers. It involves simplifying the numbers by only considering the front or leading digits and ignoring the rest. Front end estimation is typically used when a quick estimate is needed and precise calculations are not required.

For example, let's say you are at a store and you want to buy three items. The prices of the items are $8, $9, and $12. Instead of calculating the exact total, you can use front end estimation to get a rough estimate. Ignore the cents and only consider the leading digits of the prices. So, the front end estimate would be $8 + $9 + $12 = $8 + $9 + $10 = $20. This gives you a quick estimate of the total cost.

2. To add 234 and 467, you can use the traditional carrying method to ensure accuracy. Here's how:

Start by lining up the numbers vertically:

234
+ 467
_______

Begin adding from the rightmost column (ones column) by adding 4 and 7:

234
+ 467
_______

11

Write down the digit 1 and carry over the digit 1 to the next column (tens column).

Next, add the digits in the tens column: 3, plus the carried over 1:

234
+ 467
_______

11
1

Write down the digit 1 and carry over another digit 1 to the next column (hundreds column).

Finally, add the digits in the hundreds column: 2, plus the carried over 1:

234
+ 467
_______

11
1
1

Write down the digit 1 in the hundreds column and there are no more digits to add, so the final sum is 701.

Therefore, 234 + 467 = 701.
