-12. In the :guilabel:`Raster bands` section, you can select the layer by double-clicking on them. The bands are named after the raster name followed by ``@`` and band number. Since each of our rasters have only 1 band, you will the names with ``@1`` appended to the layer name. The raster calculator can apply mathematical     operations on the raster pixels. In this case we want to enter a simple formula to subtract the 2010 population from 2000. Enter the following expression. Next, click the :guilabel:`...` button next to :guilabel:`Output layer`.
+13. Select both the layers using :guilabel:`...` button as Input Layers. The raster calculator can apply mathematical operations on the raster pixels. In this case we want to enter a simple formula to subtract the 2010 population from 2000. Enter the following expression using :guilabel:`ε` button. In the expression, The bands are named after the raster name followed by ``@`` and band number. Since each of our rasters have only 1 band, you will see the names with ``@1`` appended to the layer name. Keep all the other options as default and save the output layer with the name ``population_change_2010_2000.tif`` and click :guilabel:`Run`.
