Rows and ColumnsMath brain teasers require computations to solve.
In the sum (shown below), the top row added to the middle row gives the bottom one. Working from top to bottom, remove one digit from each row, from any columns (closing the gaps) to leave three columns of digits, then a second digit from each row to leave two columns, and finally a third to leave one column so that a valid sum remains each time. What are the three sets of digits removed?
AnswerReading from top to bottom, the order of the deletions is : 8,7,6; 3,6,9; 6,8,5.
