137-136 × 1 and 138 of 139 × 138
Come on,

Is it 137-136 × 1 of 139 × 138 and 1 of 138?
137-136 × 1 of 139 × 138 and 1 of 138
=139-139 × 1 / 138-136-136 × 1 / 138
=3 - (139 + 136) × 1 / 138
=3-2 + 1 / 138
=1 / 138

Simple calculation: 139 × (137 / 138) - 137 × (1 / 138) =?

139x137/138-137x1/138
=139x137/138-137/138
=(139-1)x137/138
=138x137/138
=137

Skillful calculation of 3.75 × 138 + 1.25 × 86

3.75×138+1.25×86
=1.25×3×138+1.25×86
=1.25×（3×138+86）
=1.25×500

138 degrees 24 minutes 3 seconds - 9 degrees 36 minutes 27 seconds =?
Master to solve the problem

138 degrees 24 minutes 3 seconds - 9 degrees 36 minutes 27 seconds
=137 degrees (60 + 24) minutes 3 seconds - 9 degrees 36 minutes 27 seconds
=137 degrees 84 minutes 3 seconds - 9 degrees 36 minutes 27 seconds
=137 degrees 83 minutes (60 + 3) seconds - 9 degrees 36 minutes 27 seconds
=137 degrees 83 minutes 63 seconds - 9 degrees 36 minutes 27 seconds
=(137-9) degrees (83-36) minutes (63-27) seconds
=128 degrees 47 minutes 36 seconds
