10.5: Use Spotlight's calculations with Quick Look
Authored by: davidraso on Nov 27, '07 09:31:00AM

This is totally off topic but dfbills and the Dashboard calculator are correct.

When using a basic calculator you are only performing one calculation at a time.
1 + 2 = 3
3 * 3 = 9

The calculator does not know about the multiplication on the first calculation.
Open the Dashboard calculator push 1 + 2 * when you push * it will preform the 1+2 calculation then when you press 3 it will multiply 3 by 3. This is standard for calculators (adding machines) if it was going to preform "BEDMAS" it would display the entire equation then you would press = that would preform the calculation following the rules of operation.

Side note The calculator on the iPhone preforms calculations incorrectly. Lets say you are at dinner their are 10 people at your table and 5 people at another table, each persons tab is $20. So you take out your iphone and enter 10 + 5 * 20 = 110. Well that's not right - the iphone did not display the full equation before calculation and because the iphone doesn't have () you would have to enter 10 + 5 = * 20 = 300 (this is on my iphone with 1.1.1)

It is confusing, I know.

You're right with Dashboard, but you're wrong with the iPhone.

Basically one should assume that the mathematical order is used unless the calculator gives you the value of the intermediate operation like 3 after you add 1 and 2.

On the iPhone you omit a step on the phone by not pressing = after the addition and then continuing with the multiplication.
