To solve this problem, we need to create a "fact family" using three numbers. A fact family uses the same three numbers to make four related math facts: two addition problems and two subtraction problems.
Since the image is blank, we need to choose our own three numbers that work well together. Let's pick the numbers
3,
4, and
7.
Here is the step-by-step logic:
1.
Find the addition facts:
* We know that adding the two smaller numbers gives the big number.
* $3 + 4 = 7$
* Addition works both ways (commutative property), so we can switch the order.
* $4 + 3 = 7$
2.
Find the subtraction facts:
* Subtraction starts with the big number.
* If we take away one of the smaller numbers, we get the other one.
* $7 - 3 = 4$
* $7 - 4 = 3$
So, the four boxes in the house will be filled with these four equations.
Final Answer:
Here is one possible solution using the numbers 3, 4, and 7:
3 + 4 = 7
4 + 3 = 7
7 - 3 = 4
7 - 4 = 3
*(Note: You can use any three numbers that work, such as 2, 5, and 7, or 5, 5, and 10.)*
