• when talking about four-function calculators that do not have a stack

    Chain calculators, as the second one said in the manual

    Insisting ‘but it does have a stack!’ is the problem

    The first one does have a stack. 🙄 You refusing to see it is the problem

    And read usernames

    Your mind’s been bleached - explains a lot 😂

    The Sinclair Executive in that manual does not have an equals key

    It has a += key. If the next keypress is a number it’s interpreted as +, if the next key pressed isn’t a number, like the x button, it’s interpeted as equals Duuuuhhh It even explicitly points out to you that the result of that keypress is (a+b) 🙄

    What the fuck are you talking about?

    The example in the manual. What are you talking about? 😂

      it’s not doing 2+3x4, it’s doing 2 += 3, x= 4

      It was neither, liar. It was doing (a+b)xc, which, since it doesn’t have brackets, it tells you to do a+b=xc=, so as to evaluate the a+b first, because if you don’t press the equals at that point, and just enter a+bxc=, it will put the a+ on the the stack, and do the multiplication first, just like my calculator does

      Yeah hey which of us said += and which of us said “press the equals” afterward?

      • Yeah hey which of us said += and which of us said “press the equals” afterward?

        I said both. you said “does not have an equals key” - even though it quite clearly does, but you wanted to gaslight us into believing it doesn’t have one because it proved you were wrong 🤣🤣🤣

          • That just displays the accumulator

            Which is a single value stack, 🙄 but this calculator does indeed have a multivalue stack, so as to be able to do a+bxc, where it will put a+ on the stack (that’s two values, a and +), calculate bxc, then pop the stack and do the addition. If you instead want to do (a+b)xc, you have to press equals after a+b so that it will get evaluated before the Multiplication, because it doesn’t have Brackets keys 🙄

            (a+b)c+(d+e)f “cannot be done as a simple calculation, it must be split into two parts.” Because there’s no stack

            No, that’s because it doesn’t have any brackets keys 🙄 You can get away with one set of brackets as per the method shown, but you can’t do that with multiple brackets. You really have no idea how Maths or calculators work! 🤣🤣🤣

            Here’s an online emulator for the Sinclair Cambridge, the upgraded scientific model

            We’ve already established that’s a chain calculator Mr. needs remedial reading classes 🙄

              Chain calculators are the subject - we are talking about chain calculators - they’re the ones with only an accumulator. Comfort yourself by insisting that’s a stack, if that gets your rocks off, but the topic is calculators where 2+3*4 gets 20.

              Like it does on the Sinclair Executive, because that calculator is also a chain calculator.

              But y’know what, let’s pretend it isn’t - let’s play make-believe and say the Sinclair Executive could totes mcgoats do (a+b)c+(d+e)f, despite the very fucking short manual explicitly saying the opposite. Do you understand there are calculators that can’t? When you sneer ‘those are chain calculators,’ do you actually believe chain calculators are a thing that exists, and not just an imaginary excuse to nuh-uh at a stranger on the internet?

              • Chain calculators are the subject

                No they’re not…

                And when that was proven wrong the goalposts got moved to chain calculators, because neither of you are man enough to admit you were wrong 🙄

                we are talking about chain calculators

                You have been since you were proven wrong about all basic, non-scientific, non-graphing calculators 🙄

                they’re the ones with only an accumulator

                Which isn’t all basic, non-scientific, non-graphing calculators 🙄

                the topic is calculators where 2+3*4 gets 20

                No. the topic was…

                which was proven wrong

                say the Sinclair Executive could totes mcgoats do (a+b)c+(d+e)f

                It can’t, because no brackets keys, the calculator does have a stack, as per the manual in which (2+3)x4=20 and 2+3x4=14

                Do you understand there are calculators that can’t?

                Do you understand the claim was that none of them can?

                do you actually believe chain calculators are a thing that exists

                It’s right there in the manual! 🤣🤣🤣

                  ‘Not all basic non-scientific et cetera!’

                  Okay - but some. Yes? Some calculators are chain calculators.

                  Are you capable of discussing chain calculators, and comprehending that they have a different notation?

                  It can’t, because no brackets keys, the calculator does have a stack, as per the manual in which (2+3)x4=20 and 2+3x4=14

                  Where the fuck does the manual say 14?

                  You’d tell me a goddamn abacus has brackets in secret.
