Question 1 of 5
Amy collects 6 chestnuts. Her brother finds 7 more and adds them to her collection. How many chestnuts does Amy have now?
Why: This is a basic addition word problem. Amy starts with 6 chestnuts, and her brother adds 7 more. Adding the quantities: \(6 + 7 = 13\). Therefore, Amy has 13 chestnuts now.
Question 2 of 5
How many children sign up altogether if 13 sign up for soccer and 4 sign up for basketball?
Why: This word problem requires adding the number of children signing up for different sports. Soccer has 13 children, basketball has 4 children. Total: \(13 + 4 = 17\) children.
Question 3 of 5
Calculate \(36 + 12 = ?\) (no regrouping)
Why: Add the numbers column by column starting from the right. Tens: 3 tens + 1 ten = 4 tens. Ones: 6 ones + 2 ones = 8 ones. Result: \(36 + 12 = 48\).
Question 4 of 5
Calculate \(487 + 65 = ?\)
Why: Align the numbers by place value:\n\[ \begin{array}{r} 487 \\ + 65 \\ \hline \end{array} \]\nOnes: 7 + 5 = 12 (write 2, carry 1).\nTens: 8 + 6 + 1 = 15 (write 5, carry 1).\nHundreds: 4 + 0 + 1 = 5.\nResult: \(487 + 65 = 552\).
Question 5 of 5
Find the missing addend: \(23 + \_ = 79\)
Why: To find the missing addend, subtract the known addend from the sum: \(79 - 23 = 56\). Verify: \(23 + 56 = 79\). The missing addend is 56.
