Addition in Word Problems:

This involves using the addition arithmetic operation to solve real-life scenarios. Word problems require understanding the problem, identifying the quantities to be added, and then applying addition to find the total or combined value.

Example 1:

Liam bought 23 apples and 35 oranges. How many fruits did he buy in total?

Solution:

• Identify the numbers to add:
  • Apples: 23
  • Oranges: 35
• Add the two numbers: 23 + 35 = 58.

Final solution: Liam bought 58 fruits in total.

Example 2:

A library has 245 fiction books and 378 nonfiction books. How many books does the library have in total?

Solution:

• Identify the numbers to add:
  • Fiction books: 24
  • Non-fiction books: 37
• Add the two numbers:
  Step 1: Add the one's place: 5+8=13. Write down 3 and carry over 1.
  Step 2: Add the tens place: 4+7=11, then add the carryover: 11+1=12. Write down 2 and carry over 1.
  Step 3: Add the hundreds place: 2+3=5, then add the carryover: 5+1=6.

           245+378=623

Final solution: The library has 623 books in total.

Example 3:

A factory produced 76,581 toys in a year. Out of these, 52,473 toys were sold. How many toys remain in the factory?

Solution:

• Identify the numbers to subtract:
  • Total toys produced: 76,581
  • Toys sold: 52,473
• Subtract the numbers: 76,581−52,473=24,108.

Final solution: 24,108 toys remain in the factory.

Example 4:

Mike rode 289 miles and John rode 324 miles in a bike race. In total, how many miles did they ride?

Solution:

• Identify the numbers to add:
  • John: 324 miles
  • Mike: 289 miles
• Add the two numbers:
  Step 1: Add the one's place: 4+9=13. Write down 3 and carry over 1.
  Step 2: Add the tens place: 2+8=10, then add the carryover: 10+1=11. Write down 1 and carry over 1.
  Step 3: Add the hundreds place: 3+2=5, then add the carryover: 5+1=6.

          324+289=613

Final solution: Together, they rode 613 miles.

Example 5:

A school raised $43,258 during a fundraiser in January and $21,634 in February. In total, how much money did the school raise?

Solution:

• Identify the numbers to add:
  • January: $43,258
  • February: $21,634
• Add the numbers: 43,258+21,634=64,892

Final solution: The school raised a total of $64,892.
