Answer 1

Finding sum using most convenient combinations.

We have $1823+4282+2177+1718+9245$ $=1823+\left(2177+4282\right)+1718+9245$ (Using commutative property)

$=\left(1823+2177\right)+\left(4282+1718\right)+9245$ (Using associative property)

$$\begin{gathered} =\left(4000+6000\right)+9245 \\ =10000+9245 \\ =19245 \end{gathered}$$

Hence, the required answer is $19245$.
