Example 2:
23 x 37 = ?

$23×37 =(21+2)×37 =21× 111 3 +2×37 =7×111+74 =777+74=851$

Example 3:
532 x 37 = ?

$532×37 =(531+1)×37 =531× 111 3 +37 =177×111+37 =19647+37=19684$

### Another method

Example 4
37 x 6 = ?

$37×6 =37×3×2 =111×2=222$

Example 5
37 x 7 = ?

$37×7 =37×6+37 =37×3×2+37 =222+37=259$
