Find the absolute and percent relative uncertainty and express each answer with a reasonable number of significant figures.
(a) 6.2 (± 0.2) - 4.1 (± 0.1) = ?
(b) 9.43 (± 0.05) × 0.016 (± 0.001) = ?
(c) [6.2 (± 0.2) - 4.1 (± 0.1)] ÷ 9.43 (± 0.05) = ?
(d) 9.43 (± 0.05) ×{[6.2 (± 0.2) × 10-3] + [ 4.1 (± 0.1) ×10-3]} =?
