Topic Overview

Definitive Answer: Add whole numbers with sums up to 1,000,000 using strategies based on place value and the properties of operations.

Hey mathematicians! Today, we're going to learn how to add **multi-digit numbers** – that means numbers with lots of digits, like hundreds or thousands! It's like combining groups of things. When you add, you find the **total** or **sum** of two or more numbers. The trick is to always line up your numbers by **place value** – ones under ones, tens under tens, and hundreds under hundreds. Then, you just add each column starting from the right, one by one. It's super easy when you remember to keep everything neatly stacked!

Step-by-Step Examples

Example 1: What is the sum of 452 and 317?
  1. **Line up the numbers:** Write 452 above 317, aligning the ones, tens, and hundreds places neatly.
  2. **Add the ones column:** Start from the right. Add 2 + 7 = 9. Write 9 in the ones place of your answer.
  3. **Add the tens and hundreds columns:** Move left. Add 5 + 1 = 6 (for the tens place). Then, add 4 + 3 = 7 (for the hundreds place).
✓ Answer: 769
Example 2: Sarah has 123 red marbles and 456 blue marbles. How many marbles does she have in total?
  1. **Line up the numbers:** Write 123 above 456, making sure the ones, tens, and hundreds places are perfectly aligned.
  2. **Add the ones column:** Start from the right. Add 3 + 6 = 9. Write 9 in the ones place of your answer.
  3. **Add the tens and hundreds columns:** Move left. Add 2 + 5 = 7 (for the tens place). Then, add 1 + 4 = 5 (for the hundreds place).
✓ Answer: 579 marbles
