With a bowl of apple slices and her trusty No. 2 pencil on standby, Sigrid Brost stared intently at the computer screen Wednesday and mulled over a math problem.
45/9+6=11. Where should she place the parentheses?
"Well, 45 divided by 9 is 5," said Brost, an 11-year-old Edina student.
"Right..." boomed a slightly accented voice from her Mac.
"And 5 plus 6 is 11!" Brost declared triumphantly, scribbling the parentheses around 45/9.
"Yes, that is correct," the voice said.
It's common for students like Brost to get extra help with their homework from a tutor. But in this case, the voice on her computer belongs to Harmeet Kaur, a graduate student in Delhi, India. Twice a week for about an hour, Kaur coaches Brost on everything from long division and percentages to fractions and decimal points.
Tutor and student speak through Skype, an Internet phone service. A pen-like device and software allows both Brost and Kaur to literally write out problems on the computer screen. TutorCo, a Minnetonka-based startup company that provides the online tutoring service, can store the work and even e-mail it to Brost's parents.
