Manometer problem solving.

Homework Statement

Two pipes are connected by a manometer shown in the figure.

Homework Equations

FR = $\gamma$*hc*A

yR = yc + $\frac{I_xc}{y_c*A}$

The Attempt at a Solution

PB - PA = $\gamma$water*1.1m - $\gamma$Fluid*0.6m + $\gamma$water*0.8m = 3.33 kPa

I checked my answer and it was all okay except the answer was supposed to be -3.33 kPa. Can someone brief me on why that is?
