We begin with a 2 by 2 digit multiplication problem
First, you multiply the 2 values in the ones place. 5x7= 35, so I put my 5 in the one's place and carried my 3 tens to multiply with the tens place.
Next,you will multiply the ones place in the bottom multiply by the tens place in the top multiply. 30x7= 210, then I add the 3 and get 240.
Then, you use the 3 in the tens instead of using the 7 in the ones place. 3x5=15,so I put my 5 under the 5 in the ones place and carry the 1.
Next,you use the 3 in tens place again. 3x3=9 then I add the 1 and get 10.
Then,you add the 245 and the 105 together but, you don't add them at one time. You add the 5+5=10, so I put my 0 under the 5's and carry the 1.
Next,you add 4+0=4 then I add the 1 and get 5.
Last, you add 2+1 and then you get your answer which is 350.
Finally, you circle your answer and put product.
