103 x 107 = (100 + 3)(100 + 7) We know that (x + a)(x + b) = x^2 + (a + b)x + ab Therefore, 103 x 107 = 100^2 + (3 + 7) x 100 + 3 x 7 = 10000 + 1000 + 21 = 11021

103 +3 107 +7 .................... 11021 103 is 3 above base 100 and 107 is 7 above base 100 103+7=107+3=110 and multiply the deficiencies i.e 3 x 7=21. So, 103 107=11021.
Comments

107x103 = (105+2)x(105-2) = 105^2 - 2^2 = 11025-4 = 11021 Applying formula (a+b)x(a-b) = a^2-b^2. Here, a=105 & b=2
