Recently I came across an example for working out error propagation, and I'm having trouble following the steps:(adsbygoogle = window.adsbygoogle || []).push({});

A = 100 [tex]\pm[/tex] 1%

B = 10 [tex]\pm[/tex] 1%

AB = (100 [tex]\pm[/tex] 1%).(10 [tex]\pm[/tex] 1%)

=[tex] \left\{1000 \pm \left[\left(100.1\%\right) \pm \left(10.1\%\right)\right]\right\}[/tex]// get confused here, how does this happen?

= 1000 [tex]\pm[/tex] 1.1

= 998.9 - 1001.1

Can somebody please explain to me how the section I marked above appears.

Thank you.
