Answer 1

To find 323 + 119, you can break down 119 into 100 + 10 + 9, and add each part to 323 sequentially to make the addition easier. The final sum is 442.

Step-by-step explanation:

• To find 323 + 119 using the make ten strategy, you can break down the second number and group numbers to make tens.
• 119 can be broken down to 100 + 10 + 9. Adding this to 323 in steps, you first add the 100 to get 423.
• Then you add the 10 to get 433. Finally, adding the 9 gives you the sum 442.
• Alternatively, you could break it down further: 119 = 7 + 12 + 100, and then add these to 323 incrementally.
• 323 + 7 = 330, then add the 12 to get 342, and finally add the 100 to reach the same sum of 442.
