Question 5. 423 + __________ = 836
423 + 413 = 836

Explanation:
423 + ? = 836
Subtract the addend from the sum
836 – 423 = ?
The difference is the missing addend
836 – 423 = 413
So, the missing addend is 413
Therefore, 836 + 423 = 413

Question 6. 242 + ___________ = 739
242 + 497 = 739

Explanation:
242 + ? = 739
Subtract the addend from the sum
739 – 242 = ?
The difference is the missing addend
739 – 242 = 497
So, the missing addend is 497
Therefore, 242 + 497 = 739.

Question 7. 671 + __________ = 948
671 + 277 = 948

Explanation:
671 + ? = 948
Subtract the addend from the sum
948 – 671 = ?
The difference is the missing addend
948 – 671 = 277
So, the missing addend is 277
Therefore, 671 + 277 = 948.

Question 8. 396 + __________ = 600
396 + 204 = 600

The difference is the missing addend
600 – 396 = 204
So, the missing addend is 204
Therefore, 396 + 204 = 600.
