(Thought Wiz would appreciate a math Rant)

My old Android 4.4 phone came with a calculator that didn't do operations priority.
Ie: 2+2x4 is 8

The new Android 7.1 phone I got last year came with Google Calculator, which did operations priority.
Ie: 2+2x2 is 6

And there's no option to turn it off!

Finally downloaded a calculator which allowed you to not use operations priority.

Reverse Polish notation or get out. ;-)
The race is not always to the swift, nor the battle to the strong; but that is the way to bet.

Pretty sad that you need a calculator to solve those.

That's worrying as it's either 16: (2+2)*4 or 10: 2+(2*4) !

PS For those who remember Green Shield stamps I got a free Slide Ruler many many years ago.

I hadn't noticed that with the g-calculator.
Unlike a normal or traditional calculator, it lets you enter the whole expression before doing any calculation.

To go from left to right, ignoring the order of operations, you'll have to hit equals
So key in:
2 + 2 = x 2 =
Then you'll get 8

A traditional calculator has eager evaluation - as soon as you have two completed numbers on either side of an operator, for a 2 argument infix operator, it will calculate it.
After you hit 2 + 2 x, it will evaluate the first bit, as you know.

yes with = but thats 2 extra keys.
traditional calculator FTW!
