Just a couple more ways. If you want to retain the FALSE values, you
can choose Format/Conditional Formatting... and enter
Cell Value is equal to FALSE,
click on Format, then choose the same font color as the background
color.
If you have an IF(x, y) or IF(x, y, FALSE) constructions, where y is
numeric, you can also use the format
Format/Cells/Number/Custom 0;0;0;
to hide FALSE
