How does a calculator work step by step?
Calculators (and computers) combine inputs using electronic components called logic gates. As the name implies, a logic gate acts as a barrier in an electronic circuit; it takes in two electric currents, compares them and sends out a new current based on what it finds.
Can a calculator be wrong?
Yes, calculators can be wrong. They are nothing but simple computers and as such are only as good as their coding and will always have some limitations involving for instance rounding. Some errors can be avoided by paying attention to how you enter a problem if you are aware of the flaw in the coding.
How do I know if my calculator is working properly?
So, to determine if a calculator is accurate, you simply need to know the true value of a calculation, then compare that to the answer of the same calculation that the calculator makes . Put simply, we all know that the true answer to 2+2 is equal to 4.
Do calculators last forever?
Expect your hand-held calculator to last you at least 5-10 years, and do not be surprised if it outlives its expected lifespan! In general, if you have a solar-powered calculator you are likely to run into other issues before your battery dies.
How do I test my Casio calculator?

Why do some calculators get different answers?
The difference has something to do with the mode or the program of the calculator. For one, not all calculators follow the order-of-operations hierarchy, which leads to a different interpretation of the equation. In this case, the true form of the equation is 6/2(2+1), which yields 9.

How does a simple calculator work?
How do calculators work? A calculator is a combination of millions of logic gates arranged in particular ways that operate on numbers and produce results with lightening speed. The transistors are paired in particular ways to form logic gates, which provide specific outputs according to the placement of these transistors.
