Question

A number which by obtained by adding 0 to the number 215190

Answer 1

Let * be a binary operation on a set R. if there is a element e ∈ R such that,

a * e = a = e * a ∀ a ∈ R

Then, e is an identity element for the binary operation * on R.

Now, Consider the binary operation of addition + on Z . We know that 0 ∈ Z such that,

a + 0 = a = 0 + a ∀ a ∈ Z

So, '0' is the identity element for addition on Z.

Therefore,

215190 + 0 = 215190 = 0 + 215190

Answer 2

$\textbf {Hey there, here is the solution.}$

.............................................................................................

Define x:

Let the number be x

.

Solve x:

x + 0 = 215190

x = 215190 - 0

x = 215190

.

Answer: The number is 215190
