Multiplication where first figure is same & sum of last digits is 10.
Both numbers here start with 4 and the last figures (2 and 8 ) add up to 10. Just multiply 4 by 5 (4+1 i.e. next digit to 4 in this case) to get 20 for the first part of the answer. And we multiply the last figures: 2 x 8 = 16 to get the last part of the answer.
