1. $144$ x $44 +18$ x $46$ x $8$ – $44$ x $32 – 44$ x $58$

   $= 144$ x $44 + 144$ x $46$ – $44$ x $32-44$ x $58$

   $= 144$ x $(44+46)$ – $44$ x $(32+58)$

   $=144$ x $90$ – $44$ x $90$

   $= 90$ x $(144-44)$

   $= 90$ x $100$

   $=9000$.

2. 144 × 44 + 18 × 46 × 8 – 44 × 32 – 44 × 58

   = 144 × 44 + 144 × 46 – 44 × 32 – 44 × 58

   = 144 × ( 44 + 46 ) – 44 × ( 32 + 58 )

   = 144 ×90 – 44 × 90

   = 90 × ( 144 – 44 )

   = 90 × 100

   = 9000
