Yes, a calculator. They are on almost every computer, cell phone, tablet and smartwatch. If you dont have one of those, they even sell very small computers that only have a calculator. They can cost anywhere from a couple bucks to $100 if you buy a fancy one.

Press the = button and it will tell you how many numbers are in each group
