2. AL Khwarizmi developed a way to multiply. To multiply two decimal numbers x and y, write them next to each other, as in the figure, then repeat the following: divide the first number (left) by 2, round down the result(that is dropping the 0.5 if the number was odd), and double the second number. Keep going till the first number gets down to 1. Then strike out all the rows in which the first number is even, and add up whatever remains in the second column. Please use the above method to multiply 29 and 12, draw the figure as the given example. (10ยน) 11 13 5 26 2 52 (strike out) 1 104 143 (answer)
