Addition (Difficulty: Medium)
A durable-learning AI tutor helps students build strong understanding they can use to solve new problem or transfer learning to solve similar problem in real world.
What is 476 + 358?
Add carefully and check your regrouping.
Before choosing an answer, explain how you would figure out the total. Type your answer.
Choose your answer: Next check the Explanation and AI Feedback
Hint:
Add the ones, tens, and hundreds carefully. Watch for carrying. See explanation of addition by place value method.
Explanation:
Line up the numbers:
1 carry to hundreds
1 carry to tens
476 + 358
--------
834
AI Feedback + Sam Ortega (human expert checking) making sure no hallucination.
This is addition with regrouping in both the ones and tens places.
1 carry to hundreds
1 carry to tens
476 + 358
--------
834 correct answer
If student chose 834: correct answer
Great job! You regrouped correctly in both ones and tens.
If student chose 824: wrong answer
You may have regrouped the ones but missed the tens carry.
If student chose 814: wrong answer
This is too small - check both carries carefully.
If student chose 844: wrong answer
You may have added the tens incorrectly.
Sketch to Visualize the Addition
We add 476 and 358 using place value.
The total is 834.
Reflection:
Was regrouping in two places challenging?
Did lining up the digits help you add more accurately?
