1. A triangle has sides that measure 24 centimeters, 32 centimeters, and 40 centimeters. What is the total distance around the triangle? Answer: 96 centimeters Solution: Identify the lengths of all three sides: 24 cm, 32 cm, and 40 cm. Add the three side lengths together to find the perimeter. Calculate 24 + 32 = 56.
   Full step-by-step solution

   Step 1: Identify the lengths of all three sides: 24 cm, 32 cm, and 40 cm. Step 2: Add the three side lengths together to find the perimeter. Step 3: Calculate 24 + 32 = 56. Step 4: Calculate 56 + 40 = 96. Step 5: The total distance around the triangle is 96 centimeters.

2. Noah collected 52 seashells at the beach in the morning. In the afternoon, he found 37 more seashells. How many seashells did Noah collect in total? Answer: 89 seashells Solution: Noah collected 52 seashells in the morning. He collected 37 more seashells in the afternoon.
   Full step-by-step solution

   Step 1: Noah collected 52 seashells in the morning. Step 2: He collected 37 more seashells in the afternoon. Step 3: Add the two amounts together: 52 + 37 Step 4: First add the ones: 2 + 7 = 9 Step 5: Then add the tens: 50 + 30 = 80 Step 6: Combine the results: 80 + 9 = 89 Noah collected 89 seashells in total.

3. 72 - 48 = ? Answer: 24 Solution: Write the problem vertically: 72 - 48. Look at the ones column: 2 - 8. Since 2 is smaller than 8, we need to borrow from the tens column.
   Full step-by-step solution

   Step 1: Write the problem vertically: 72 - 48. Step 2: Look at the ones column: 2 - 8. Since 2 is smaller than 8, we need to borrow from the tens column. Step 3: Borrow 1 from the 7 in the tens column. The 7 becomes 6, and the 2 in the ones column becomes 12. Step 4: Now subtract the ones column: 12 - 8 = 4. Step 5: Now subtract the tens column: 6 - 4 = 2. Step 6: Combine the results from the tens and ones columns: 2 tens and 4 ones is 24. The answer is 24.

4. Noah collected 57 seashells at the beach in the morning. In the afternoon, he found 34 more seashells. How many seashells did Noah collect in total? Answer: 91 seashells Solution: Noah collected 57 seashells in the morning. He collected 34 more seashells in the afternoon.
   Full step-by-step solution

   Step 1: Noah collected 57 seashells in the morning. Step 2: He collected 34 more seashells in the afternoon. Step 3: Add the two amounts together: 57 + 34 Step 4: First add the ones: 7 + 4 = 11 (write down 1, carry over 1 to the tens) Step 5: Then add the tens: 5 + 3 + 1 (carried over) = 9 Step 6: Combine the tens and ones: 90 + 1 = 91 Noah collected 91 seashells in total.

5. Noah has 68 marbles in his collection. His friend Lily gives him 25 more marbles. How many marbles does Noah have now? Answer: 93 marbles Solution: Noah starts with 68 marbles Lily gives him 25 more marbles Add the ones place: 8 + 5 = 13 (write down 3, carry over 1 to tens place) Add the tens place: 6 + 2 + 1 (carried over) = 9 Combine the tens and ones: 90 + 3 = 93 Noah has 93 marbles in total.
   Full step-by-step solution

   Step 1: Noah starts with 68 marbles Step 2: Lily gives him 25 more marbles Step 3: Add the ones place: 8 + 5 = 13 (write down 3, carry over 1 to tens place) Step 4: Add the tens place: 6 + 2 + 1 (carried over) = 9 Step 5: Combine the tens and ones: 90 + 3 = 93 Noah has 93 marbles in total.

6. Noah has 68 crayons in his box. He finds 24 more crayons under his desk. How many crayons does Noah have in total? Answer: 92 crayons Solution: Start with 68 crayons Add 24 more crayons Add the tens: 60 + 20 = 80 Add the ones: 8 + 4 = 12 Combine the results: 80 + 12 = 92 Noah has 92 crayons in total.
   Full step-by-step solution

   Step 1: Start with 68 crayons Step 2: Add 24 more crayons Step 3: Add the tens: 60 + 20 = 80 Step 4: Add the ones: 8 + 4 = 12 Step 5: Combine the results: 80 + 12 = 92 Noah has 92 crayons in total.

   Full step-by-step solution

   Step 1: The baker has 72 chocolate chip cookies and 56 oatmeal raisin cookies. Step 2: To find how many more chocolate chip cookies there are, subtract the number of oatmeal raisin cookies from the number of chocolate chip cookies. Step 3: 72 - 56 = 16 Step 4: The baker has 16 more chocolate chip cookies than oatmeal raisin cookies. The answer is 16 cookies.

10. 72 - 45 = ? Answer: 27 Solution: Start with 72 - 45. Look at the ones place: 2 - 5. Since 2 is smaller than 5, we need to regroup from the tens place.
    Full step-by-step solution

    Step 1: Start with 72 - 45. Step 2: Look at the ones place: 2 - 5. Since 2 is smaller than 5, we need to regroup from the tens place. Step 3: Take one ten from the 7 tens, which leaves 6 tens. Add that ten to the 2 ones, making 12 ones. Step 4: Now subtract the ones: 12 - 5 = 7. Step 5: Now subtract the tens: 6 (from the regrouped tens) - 4 = 2. Step 6: Combine the tens and ones: 2 tens and 7 ones is 27. The answer is 27.
