What is four divided by four?

Answer 1

Four divided by four is equal to one. When you divide a number by itself, the result is always one, as each part is equal to the whole. In this case, four divided by four equals one because there is one four in four.

Answer 2

Why such simpler questions? Is there any riddle with this? As we divide a by a then we write the solution as a 1-1 = a 0

Same way 4/4 = 40

But primary school student gives me 1 as the solution for 4/4. So I am compeled to come to the conclusion that 40 = 1 So I generalise this as any real number with 0 raised as index the value will become as 1. So (mathematics)0 = 1.
