Question

The value of $\left\{2.32\right\}-\left\{3.44\right\}+\{-1.35\}+\{-2.22\}$ is
(where $\{.\}$ represents fractional part function)

Answer 1

$\left\{2.32\right\}-\left\{3.44\right\}+\{-1.35\}+\{-2.22\}$
$\left\{2.32\right\}=0.32\left\{3.44\right\}=0.44\{-1.35\}=1-0.35=0.65\{-2.22\}=3-2.22=0.78$

$\left\{2.32\right\}-\left\{3.44\right\}+\{-1.35\}+\{-2.22\}=0.32-0.44+0.65+0.78=1.31$
