which property that 25+ (-10) + 25 represents ? give reasons.
Find (n) (4000-5000) + 6000 (in 4000 + (5000+6000 (mm) (4000-6000)​

Answer 1

Answer:

Additive identity is a number, which when added to any number, gives the sum as the number itself. It means that additive identity is “0” as adding 0 to any number, gives the sum as the number itself.

Example:

2 + 0 = 2

0 + 5 = 5

For any set of numbers, that is, all integers, rational numbers, complex numbers, the additive identity is 0. It is because when you add 0 to any number; it doesn’t change the number and keeps its identity.

Therefore, a + 0 = 0 + a = a

Where, a is any number.
