when i was young, i use scratch book instead of calculator to do math and now people use google instead of calculator to do math

I could be very very wrong about this, but as I understand it, while 0^0 is technically undefined, it's often defined as 1 to simplify certain problems.
No, it's not. Please do not let this thread turn in another debate about 48÷2(9+3) or this thread will be locked. See here for the "infamous equation": https://www.physicsforums.com/showthread.php?t=494675 See here for [itex]0^0[/itex]: https://www.physicsforums.com/showthread.php?t=530207
Wolframalpha is the the best resource out there for a lazy person who doesn't care about his math skills. Yes, google can't be trusted.
It has so many values for physical constants that are outdated or flat-out wrong. Avogadro's number, the astronomical unit, Newton's gravitational constant, pick one: It's probably wrong to some degree or another. For example, the google calculator value for the AU differs from the published value by 129 kilometers. The uncertainty in the published value is 3 meters.
