Acording to Mathmetica which I consider the last word on maths 0^0 is inditerminate

Ok. They don't change the result much.

But multiplying them with a constant infinitesimally close to 1, or adding them with a constant infinitesimally close to 0 doesn't change the result.Oh yes it does! (1 * Δ)^{2} = Δ^{2} ≠ 1(1+Δ) ^{2} = 1 + 2Δ + Δ^{2} ≠ 1.Ok. They don't change the result much.

Squeeze the trigger slowly and you'll appreciate the enormous difference between "not much" and "unstable".

It isn't. Only you suggested it was.

You mentioned that 0 x 0 was very stable but that depends on how you measure stability.

0 * 0 is extremely stable. The operands can be perturbed heavily without changing the result (e.g. by multiplying them with some constants). Adding one of the operands with a finite constant doesn't change the result. Adding both operands with a finite constant does change the result.

Anyway, using this notion of proportional difference, 0 x 0 and also 0 + 0 isn't stable, it's terrifyingly unstable. Perturb the input numbers even a tiny amount and you generate a proportional difference that is unbounded. No other choice of input numbers is that bad.

A simple example of a trigger instability is the equation y = 1/x. As x passes through zero its value switches between +∞ and -∞.

There are seven indeterminate forms involving 0, 1, and infinity:https://mathworld.wolfram.com/Indeterminate.htmlIf complex infinity is allowed as well, then six additional indeterminate forms result:

0 + 0 = 0 = the expected answer for 0 + 0.Perturb the input values slightly and consider δ + ε where δ, ε are arbitrarily small but positive.Then δ + ε ≠ 0, instead δ + ε = something small but positive. The percentage change from the expected answer, 0, is then undefined: (something positive) / 0 x 100% - the division by 0 is a problem.Best Wishes.

Perturbation by multiplication already implies ratio. Percentage change simply converts perturbation from addition to multiplication.

0^0 is highly debated in the mathematical community. Why is 0^0 undefined? Does 0^0=0? Does 0^0=1? In this video I'll address the 0^0 meaning and give you a solid 0^0 proof. SPOILER ALERT: 0^0=1 proof can be found just using the definition of how we define exponents.
