Red 2750 Maroon Sneaker Women's Cotu Superga Frequently Asked Questions

Cotu 2750 Superga Red Maroon Sneaker Women's 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!

The History of calculators
