Can't figure out what I did wrong.....

Here's the formula... The answer should be 4, which should be W

S=10
T=5
w=4

w=33-(10 - 0.28 x S + square root of 28xS ) x ( 33 - T ) / 22.727

so.. the square root symbol was over top of 28 and S just don't know how to put that symbol in here...

so.. you work from left to right... and you do what's in the ( ) first.. .soo...

10 - 0.28 = 9.72 x 10 (which is S) = 97.2

then you add that to the sq root of 28x10 so.. 28x10= 280 the sqroot of that is.. 16.7332

sooo.... 97.2 + 16.7332 = 113.9332

then.... you do the other ( ) which is 33- 5 (T) = 28

so.....

113.9332 x 28 = 3190.1296

then you do the rest...

3190.1296 = 140.36738
22.727

W = 33 - 140.36738

W = -107.36738

The answer I keep getting is W = -107.36738

what did I do wrong?
