Find the Missing Addend to Complete the Equation!

What is the missing addend for each equation?

1. 5 + (-9) = -7

2. 9 + 6 = 0

3. (-7) + _____ = 0

4. (-4) + _____ = -11

Answers:

1. The missing addend for 5 + (-9) = -7 is -3 (Option a).

2. The missing addend for 9 + 6 = 0 is -7 (Option a).

3. The missing addend for (-7) + _____ = 0 is 7 (Option b).

4. The missing addend for (-4) + _____ = -11 is 3 (Option d).

Understanding how to find missing addends in equations is a crucial skill in mathematics. These problems help strengthen our basic algebraic skills and logical thinking.

Explanation:

The equations presented require us to identify the number that, when added to the given number, completes the equation. In the case of 5 + (-9) = -7, we can subtract 5 from -7 to find the missing addend of -3 (Option a).

Similarly, in the other equations, following the same method reveals the missing addends to be -7 (Option a), 7 (Option b), and 3 (Option d) respectively.

By practicing these types of problems, we can enhance our mathematical skills and problem-solving abilities.
