Weather is a little cold here, so I'll stick to high-low poker for now. [hint]I was born in the 1940's and learned my math scratching a rock on a coal shovel. I get 110.
Take 79 bicycle helmets and add 40 more. That's 119. Now subtract your age. If the answer was the last two digits of the year you were born, you deserve to own an ebike for your birthday. If it wasn't then you already had your birthday. Did you get an ebike?
Both could be correct (dependent on the calculator)? Of course a human using math or most calculators will respect the order of operations (just put it in Excel as you wrote it and the answer is 120....Python too). But I think there are some programming languages out there that operate simply on a left to right basis. In which case the answer is 5.Who is right?
230 - 220 ÷ 2 =
I say it is 120
A math PhD says it is 5!
