asked • 10/04/17In the last step of a computation, Evelyn added 290 instead of subtracting 290. What one number can she subtract from her final result of 3,710 so that the correct result of the computation is displayed on the calculator and she does not have to clear her calculator and does not have to clear her calculator and start over?
