I am writing functions with the following equation:

1. P = 10 ^ (A - B9 / ( T C ))
2. Z = C * Exp ( -k * t)

I am using the following syntax:

Answer 1:

Function P(a As Integer, b As Integer, c As Integer, t As Integer) As Integer
    P = (10 ^ a) / 10 ^ (b / (t   c))
End Function

Answer 2:

Function Z(c As Integer, k As Integer, t As Integer) As Integer
    Z = c / Exp(-k * t)
End Function

The answers are not coming out as accurate.

Please let me know where I am lacking.

The equations are different from the original, you should also post the expected result from certain numbers, try this:

Function P(a As Integer, b As Integer, c As Integer, t As Integer) As Integer
    P = 10 ^ (a - b / (t   c))
End Function

Function Z(c As Integer, k As Integer, t As Integer) As Integer
    Z = c * Exp(-k * t)
End Function

Also you must take into account the max value that holds the Integer that is: 32767 so the program will overflow when that variable exceeds that value, you can read more about data limits here
