Seek The Multiplication Treasure 2009-2010 Copy this problem. Multiply the factors in the top row by the digit in the ones place in the second factor. 342 x 23 1 342 x 3 1026 Since 4 • 3=12 Carry the 1 and write 4 down Multiply Multiply Multiply •33 ••the 23 +2 1 Now you will multiply the top factor by the tens digit in the second factor. In this problem, you multiply by the 2 in the tens place or 20. 342 x 23 342 x 23 1026 Since the 2 actually represents 2 tens or 20, we will want to put a zero in the ones place in the second row of our work before we multiply anything else. 342 x 23 342 x 23 1026 0 Multiply the 2 times every digit in the top factor and write the answer in the second row below the line. 342 x 23 342 x 23 1026 6 84 0 To check to see if you are ready to add, count the number of digits in the second factor. 342 x 23 There are two digits in the second factor. 342 x 23 1026 6 84 0 Since there are two digits in the second factor there should be two rows of numbers to add to get the product. 342 x 23 There are two digits in the second factor. 342 x 23 1026 6 84 0 one two Since the number of digits matches the number of rows, we now add the rows together to get the product of the original problem. 342 x 23 There are two digits in the second factor. 342 x 23 1026 + 6 84 0 one two Since the number of digits matches the number of rows, we now add the rows together to get the product of the original problem. 342 x 23 342 x 23 1026 + 6 84 0 7866 Work the following problem following the steps used in the previous problem. 914 x 48 Work the following problem following the steps used in the previous problem. 1 914 x 48 7312 + 36560 43,872 Work the following problem following the steps used in the previous problem. 55 66 767 x 89 6903 + 61360 68,263 Are you up to the adventure of finding the multiplication treasure?
