Solve for a a+0=a

$a + 0 = a$

Step 1

Add $a$ and $0$ .

$a = a$

Step 2

Move all terms containing $a$ to the left side of the equation.

Subtract $a$ from both sides of the equation.

$a - a = 0$

Subtract $a$ from $a$ .

$0 = 0$

Step 3

Since $0 = 0$ , the equation will always be true for any value of $a$ .

All real numbers

Step 4

The result can be shown in multiple forms.
