Why is the Apple calculator app not on the iPad?

iPad doesn’t have a built-in App - however, there are many excellent third-party Calculator Apps available from the App Store.

One of the very best calculators in the App Store - that happens also to be both completely free and without any advertisements whatsoever - is Sci:Pro Calculator:

For a “paid” alternative, perhaps consider PCalc:

Before the first iPad in 2010, Apple's development team did have an iPad calculator ready to go, but it was just a scaled-up version of the iPhone app. Steve Jobs caught wind of it and quickly nixed it, and there wasn't enough time to design an iPad-optimized calculator before the iPad hit shelves.
