Why does my calculator 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.
Can calculators be wrong?
I think most people would say that barring any physical damage to the calculator (dropping it, exposing it to extreme heat or cold, etc.), all calculators are accurate 99.99% of the time.
How do you confuse calculator?
If you get a number greater than 9, add the digits up again. For example, if the number is 34291 , we add the digits up (3 + 4 + 2 + 9 + 1) and get 19 ; add those digits (1 + 9) and get 10 ; add those digits (1 + 0) and get 1 ; so the remainder when dividing by 9 would be 1.
How do calculators know all the answers?
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.
What words can you spell on a calculator?
