About SumStreak

A small daily habit for keeping your arithmetic quick.

What it is

SumStreak gives everyone the same 20 arithmetic problems each day: five each of addition, subtraction, multiplication and division, getting harder within each round. Answers move on by themselves when they're right, so your score is just your time. Then you get a grid showing how fast each problem went, to keep or to share.

It's built for people who want to get quicker with numbers in a couple of minutes a day: adults keeping sharp, students who need speed in tests, and teachers looking for a class warm-up.
