Advantage
• Instead of calculating we recall from memory.
• For e.g. 12 x 12 = 144, we recall, instead of
calculation.
• In recalling the chances of mistake is less.
• Recall is much faster than calculation.
• Always add two single digits in shuddha method of
addition, which can be recalled after due practice.
