Video Summary

Renate removed several numbers from the table shown on the right, so that the sum of the remaining numbers in each row and each column is 15. What is the sum of the numbers she removed? Okay, so we can sum up all the numbers in our table right now, row by row. So in the first row, we have 22. Second row, we have 19. Third row, we have 20. And in the fourth row, we have 24. Now, summing all of these up, we get 85. Now, assuming that if each row had a sum of 15, that would mean just our total sum of numbers would be 15 times 4, which would be 60. Now, we can see that we have an excess of 85 minus 60, which is 25. So, the sum of the numbers she removed must be D25.
