How do you calculate the delta between two numbers?

If you have a random pair of numbers and you want to know the delta – or difference – between them, just subtract the smaller one from the larger one. For example, the delta between 3 and 6 is (6 – 3) = 3. If one of the numbers is negative, add the two numbers together.

So, “Δx” means “the change in movement.” Scientists make use of this mathematical meaning of delta in various branches of science.

What is a delta in data?

Delta encoding is a way of storing or transmitting data in the form of differences (deltas) between sequential data rather than complete files; more generally this is known as data differencing. … The differences are recorded in discrete files called “deltas” or “diffs”.
