: Multiplication by a negative constant didn't seem right either so I fixed that. Thanks. --[[User:Paddy3118|Paddy3118]] 12:44, 17 August 2011 (UTC)
:: It's not pertinent to current task, but a negative uncertainty does have meaning if correlation is considered. If <math>a\equiv a_0\pm\sigma</math>, you can say <math>-a=-a_0\pm(-\sigma)</math>, and the sum <math>a + (-a) = 0\pm 0</math> (note how the <math>\sigma</math>s just add, not RMS). --[[User:Ledrug|Ledrug]] 12:58, 17 August 2011 (UTC)
