2750 Women's Cotu Red Maroon Sneaker Superga I tried to calculate 2+2x2 and got 8. Maybe the online calculator does not work correctly?
The calculator works correctly! The matter is that the calculator calculates the subtotal when you perform each subsequent mathematical operation (addition, subtraction, etc.). Look at the current operation display located to the right under the main display.
Calculations are as follows: 2+2=4, and subtotal is 4. 4х2=8, so, the final result is 8. There are no errors!

Presumably, the first Abacus appeared in ancient Babylon about 3 thousand years BC. In Ancient Greece, abacus appeared in the 5th century BC.
