"I have just noticed something I hadnâ€™t realised about the Windows calculator. When running in standard mode it operates LTR (2+3x5=25) while in scientific mode it obeys the normal order of operations (2+3x5=17). Worth knowing when learning about BIDMAS or PEMDAS

"And the sad thing is that I still remember some of these calculators that are now museum exhibits.
I took these photographs in the Whipple Museum of the History of Science in Cambridge in July 2019"
