Exponential Growth and Decay Worksheet

Let A be the starting value, r% be the rate that its growing and t be the time. And we have the formula A(1+r %)^t which is for growth. So let's say it is equal to Y which is the value after its growth. Why is it that we can't get the correct value when we use the decay formula to find back A so in this case it would be Y(1-r%)^t=A...but it doesn't work and it is just some value that is close to A but not exactly A and I don't understand why
