The image contains a series of simple arithmetic equations. Here's a breakdown of the equations:

1. $16 - 5 = 11$
2. $1 + 4 + 6 = 10$
3. $2 + 3 + 6 = 11$
4. $3 + 4 + 5 = 12$
5. $2 + 4 +$ (unclear digit) $= 11$

In the fifth equation, the third number is slightly obscured but looks like it could be "5", which makes the equation correct, since $2 + 4 + 5 = 11$.

2. Can you write more examples of arithmetic equations with different combinations of numbers?
3. How does changing the order of numbers affect addition results (commutative property)?
4. What happens when you combine both addition and subtraction in a single equation?
5. How can arithmetic be applied in real-world problems?

Tip: When solving arithmetic problems, always check your final result by working backwards to see if the operations hold true.
