We need to add 4 and 7 together. We can visualize this with dots. Here are 4 blue dots and 7 red dots. When we combine them all together, we get 11 green dots. So 4 plus 7 equals 11.
Another way to solve 4 plus 7 is using a number line. We start at position 4, then count 7 steps forward. Each step moves us one number to the right. After 7 steps, we land on 11. This confirms our answer: 4 plus 7 equals 11.
Now let's write this mathematically. We have 4 plus 7 equals question mark. The answer is 11, so 4 plus 7 equals 11. We can verify this by checking: 11 minus 7 equals 4, and 11 minus 4 equals 7. Both are correct, confirming our answer.
Addition has important properties. One key property is the commutative property, which means we can change the order of numbers without changing the result. So 4 plus 7 equals 11, and 7 plus 4 also equals 11. The order doesn't matter in addition.
In conclusion, 4 plus 7 equals 11. We've demonstrated this using visual counting, number line method, mathematical notation, and the commutative property. All approaches lead to the same answer: eleven. This shows how mathematics provides multiple ways to solve the same problem and verify our results.
