Ok, boss. Here's your math. Really wonder what they teach you folks these days...
What we have
temp = weight + sumweight
delta = x - mean
R = delta * weight / temp
mean = mean + R
What we want to show
sumweight * delta * R = weight * delta * (x−mean)
sumweight * delta * R = weight * delta * (x−(x-delta+R))
sumweight * delta * delta * weight / temp = weight * delta * (x−(x-delta+R))
sumweight * delta * delta * weight / temp = weight * delta * (x−x+delta-R))
delta * weight * sumweight * delta / temp = weight * delta * (delta-delta * weight / temp)
weight * delta * sumweight * delta / temp = weight * delta * (delta-delta * weight / temp)
weight * delta * sumweight * delta / temp = weight * delta * delta * (1 - weight / temp)
weight * delta * delta * sumweight / temp = weight * delta * delta * (1 - weight / temp)
weight * delta * delta * sumweight / temp = weight * delta * delta * (1 - weight / temp)
weight * delta * delta * sumweight / temp = weight * delta * delta * (temp - weight) / temp
weight * delta * delta * sumweight / temp = weight * delta * delta * sumweight / temp
