Trying to tally your grocery bill as you shop? Need to cut a recipe by one-third? Stumped by your kid’s homework assignment? Try talking aloud as you do the math. When researchers from the University of Granada in Spain videotaped students working on tough math problems, those who spoke aloud while doing the equations found the correct answers faster than those who did the problems in their head. This easy technique helps you understand the problem better and come up with new ways to reach the right solution, the researchers say.
