Solving by distribution method of multiplication on addition – 

(i) 138 × 101 = 138 × (100 + 1) 

= 138 × 100 + 138 × 1 = 13800 + 138 = 13938 

(ii) 125 × 400 = 125 × (300 + 100) 

= 125 × 300 + 125 × 100 = 37500 + 12500 = 50000 

(iii) 608 × 35 = 608 × (30 + 5) 

= 608 × 30 + 608 × 5 = 18240 + 3040 = 21280
