what is a + a?

If you have an apple and an apple, what do you have ?

No, you have 2 apples, not 2

1 apple + 1 apple = 2 apples
Ѽ + Ѽ = 2Ѽ
π + π = 2π

so

a+a = 2a

yeah thats what i meant but thanks

How did you make an apple come up? I can copy and paste your apple like this:Ѽbut how do you make it and other stuff?

To find the value of "a + a," you need to perform addition. Adding "a" to itself can be simplified as multiplying "a" by 2. Therefore, the expression "a + a" is equal to 2a.
