Frequently Asked Question: Understanding Calculation Order

Question: Why does 2+2×2 equal 8 on this calculator?

Answer: Our free calculator online performs calculations in the order you enter them. It doesn’t follow the standard order of operations (PEMDAS/BODMAS) automatically.

In the example of 2+2×2, the calculator processes it step-by-step:

2 + 2 = 4 (subtotal displayed)
4 x 2 = 8 (final answer)

To perform calculations following the standard order of operations, you would need to input them differently or utilize a scientific calculator for more advanced functions. This simple operational order makes our free calculator online exceptionally straightforward for basic calculations.

A Glimpse into Calculator History

While our free calculator online represents modern convenience, the concept of calculating devices has ancient roots. The abacus, considered the ancestor of the modern calculator, dates back thousands of years.

The abacus, derived from the Latin word for “board,” was a counting tool consisting of a frame with beads or stones that could be moved along rods or grooves. Believed to have originated in ancient Babylon around 3000 BC, the abacus was also used in ancient Greece as early as the 5th century BC.

From the abacus to today’s free calculator online, the need for efficient calculation tools has been a constant throughout history. We are proud to offer a modern, accessible solution for your everyday mathematical needs.
