Multiplication using identities Distributive property . a x (b + c) (a x b) + (ax c) 11 x 26 = 26 x (10 +1)-260 + 26 = 286 7 x 212 = 7 x (200 + 12) = 1400 + 84 = 1484 180x15= 180 x (10+5) = 1800+900-2700 .

(a + b) x (a-b)=a2-b2 + ab-ab b- a a2 b Eg:85 x 25 = (30 + 5) x (80-5)-302-52 . = 900-25 = 875 * "If b = 1 then ?? 31 x 29 k a 302-1 = 900-1 899

Multiplication of numbers (BASE METHOD) 10: Eg: 6 x 8 P 6 (-4) . Base 1. Multiply right column numbers 2. Add the diagonal numbers (-4) x (-2)-8 and 64(-2)-84 (-4) = 4 8 (-2) X (-2)8 an

Eg 2: 14x 16 14 +4 16 +6 14 x 16 224 20 +2 4

Eg 3: 14x 8 14 04 08 (-2) 12 (-8) 14x8=120+(-8) = 112

. Base 100: Eg: 105 x 101 105 05 101 01 Base = 100 has two zeroes, so 05 106 / 05 105 x 101 = 10605

Eg: 104 x 93 104 04 93 (-7) 97 /(-28) 104 x 93- 9700+ (-28) 9672
