I have a lot of data and I want to make an account with them. I calculate x, then y. When I calculate x times y, the count is going wrong, why?? Sounds like something simple, where did I multiply it wrong, please?
z = 0.5
a=0.1
a2= 43
b=0.15
b2 = 40
c = 0.20
c2 = 38
d = 0.25
d2 = 36
e = 0.30
e2 = 34
f= 0.35
f2 = 33
g = 0.40
g2 = 31
h = 0.45
h2 = 30
i = 0.50
i2= 28
um = (1/z**2)*9
print('um=',um)
x = (a/z**2)+(b/z**2)+(c/z**2)+(d/z**2)+(e/z**2)+(f/z**2)+(g/z**2)+(h/z**2)+(i/z**2)
print('x=',(1/um)*x)
y = (a2/z**2)+(b2/z**2)+(c2/z**2)+(d2/z**2)+(e2/z**2)+(f2/z**2)+(g2/z**2)+(h2/z**2)+(i2/z**2)
print('y=',(1/um)*y)
#Final
print(x*y)
>Solution :
It seems that you did
print('x=',(1/um)*x)
and
print('y=',(1/um)*y)
Then, when you multiplied x*y, you actually multiplied different values in comparison to what you printed.
As I understand, for it to be correct you would need something like
print(((1/um)*x)*((1/um)*y))
or
r_um = 1/um
print((r_um*x)*(r_um*y))
