Question about Casio fx-300ES Calculator
I know the answer to this is 1.129 but the closest I get is 1.49965 by putting the formula in the calculator in pieces!
The expression that gives you the result you were looking for is as in the screen capture.
It is to say the least a very clumsy way to write it and I am not surprised you made mistakes typing it. I would too.
At leats unclutter the expression by removing all those 1 before a parenthesis. If there is nothing explicitely written before a parenthesis it is always 1x the content of the parentheses.
That is what it looks like after removing the redundant 1x
You can still do better by computing the differences inside the varunable to enter a formula correctly to get the rig - 3704b12.jpgal parentheses. (1-0.3)=0.7
You can still arrange it further. And I leave it to you.
Having a calculator is not a sufficient reason to park the brain in idle gear.
