VEDIC MATHS :Multiplying by sixteen
First, multiply the number in question by 10. Then multiply half the number by 10. Then add those two results together with the number itself to get your final answer. For example: 16 × 24 Step 1: 24 × 10 = 240 Step 2: (24 × 1/2) × 10 = 12 × 10 = 120 Step 3: add steps 1 and 2 and the number = 240 + 120 + 24 = 384
