Microsoft's calculator can not count?

Hi,

The standard calculator has given a result and Wissenschaffticher calculator another?

Funny.
The one on the right seems obviously wrong. It reads left to right and executes operations not taking in account operators precedence.
So, 2*8 =16 +2 = 18 *8 =144
I would write a "random" calculator where the operators order would be...random!

udg

it has to do with how you enter the "formula" and how it interpreters it...
your formula, entered as is, is being seen by the first calculator as two times 8x2 added together, while the other sees three distinct operations:

(8*2)+(8*2)=32, same result in every calculator
((8*2)+8)*2=48, same result in every calculator

you are entering a series of operations and the results may or may not take into account the previous operation.
in my android default calculator, when I enter 8*2 it automatically shows a result preview = 16, when I start typing the rest of the "formula"
8*2+8 it previews 24

I guess, a math result can only be as accurate as the formula entered, like in my case, I just change the operators order from 2*8 to 8*2

It is already clear to me, it looks but still comical.

The question is: Y U not able to calculate 16 + 16 without help?

No, I can only to 10, I only have 10 fingers.

It's still summer time (in Europe) so you can take off your shoes and reach 20 easily!
And counting your nose you can reach 21 and counting your... no, limit your math to 20, it's better .. eheheh

BTW, I tried the MS Calculator in W7 and it doesn't know about operators precedence too. At least MS is coherent with itself!

Order of Operations

The scientific calc does the equation like this: (2 * 8) + (2 * 8) = 32
The "normal" calc does the equation like this: 2 * 8 + 2 * 8 = 144
