40th anniversary of the handheld calculator.

Anyone a certain age, saw the emergence of the calculator.

Anyone below a certain age, take this for granted.

But it was only 40 years ago that the first handheld calculator was introduced by Texas Instruments.

Over the years, I must have bought some (20+) plus calculators (all T.I. as I recall), yes I like calculator (the more powerful, the better).
