(b) 57 × 57

(AB – 100, WB – 100/2 = 50)

(c) 395 × 396

(AB -100, WB -100 × 4 = 400)

(d) 228 × 246

(AB - 1000, WB - 1000/4 = 250)

(e) 45 × 45

(AB -10, WB -10 × 4 = 40)

(f) 58 × 42

(AB - 10, WB - 10 × 5 = 50)

(g) 55 × 45

(AB - 100, WB -100/2 = 50)

(h) 45 × 42 (Important)

(AB - 100, WB - 100/2 = 50)

(i) 245 × 248 (Important)

(AB - 1000, WB - 1000/4)

Have a look at examples (h) and (i). In example (h), the actual base is 100 and the working base is 50. The answer obtained is 3740 and the LHS when divided by 2 gives an answer 181/2. However, we cannot have a fraction in the final answer. Hence, we multiply the fraction by the actual base and add it to the RHS. In this case, the fraction 1/2 is multiplied by the actual base 100 (1/2 × 100 = 50) and the answer is added to the RHS. The RHS now becomes 50 plus 40 equal to 90.

In example (i) the actual base is 1000 and the working base is 250. The LHS of the answer, namely, 243 when divided by 4 gives 603/4. The fraction is multiplied by the actual base and added to the RHS. Thus, 3/4 multiplied by 1000 gives 750 which is added to the RHS. The RHS now becomes 10 + 750 = 760.

With this we complete our study of the Base Method. We have studied all the different cases in which the Base Method can be applied with a sufficient number of solved examples. The last sub-section appears a little confusing at first sight but you will be able to tackle problems after some practice.

Given below is a comparison — the traditional system of multiplication with the Vedic method studied in this chapter.
