P.S. I have no idea why you’re so skeptical that the Sinclair Executive can execute other than left-to-right, to the point of reading an example where the operations are executed left-to-right as evidence that it can execute in another order. But if you really cannot accept, due to some weird glitch in your programming or whatever, what about:
The Monroe 20. The example is typed in as 1 + 2 × 4 - 5 ÷ 6 = and the result is given as 1.16 (repeating). That has been executed left-to-right; the result would be 8.16 (repeating) if executed with the usual operator precedence.
The Montgomery Ward P300. An example is typed in as 8.3 + 2 ÷ 4 - 6.8 =, with the result given being -4.225. That has been executed left-to-right; the result would be 2 if executed with the usual operator precedence.
The Omron 88. An example is typed in as 98 + 76 - 54 × 32 ÷ 10 =, with the result being given as 384. That has been executed left-to-right; the result would be 1.2 if executed with the usual operator precedence.
I mean, it’s just like I said: the basic, four-function calculators are all like this. Feel free to browse more manuals on that website if you want, it’s quite interesting! If you were to, you’d have a better understanding of how these calculators - which I practised with in primary school, but which you, because you didn’t, assert don’t exist - actually work.
