let's multiply seven seven times 253 and see what we get so just like in the last example what I like to do is I like to rewrite the first the largest number first so that's 253 and then write the smaller number below it and align the place value the seven it only has a ones place so I'll put the seven right over here below the ones place in 253 and then put the multiplication symbol right over here so you could read this as 253 times seven which we know is the same thing as 7 times 253 and now we are ready to compute and there are many ways of doing this but this would you could call the standard way so what I do is I start with my 7 and I multiply it times each of the numbers up here and I carry appropriately so first I start with 7 times 3 well 7 times 3 we know is 21 let me write that down 7 times 3 is equal to 21 you could do this part in your head but I just want to make it clear where I'm getting these numbers from what I would do in the standard method is I would write the 1 into 21 down here but then carry the 2 to the tens place now I want to figure out what 7 times 5 is now I want to figure out what 7 times 5 is we know from our multiplication tables that 7 times 5 is equal to 35 now we can't just somehow put the 35 down here we still have to deal with this 2 that we carried so we compute 7 times 5 is 35 but then we also add that 2 so it's 35 plus 2 is 37 now we write the 7 right over here in the tens place and carry the 3 carry the 3 now now we need to compute what 7 times 2 is we know that 7 times 2 is 14 from our multiplication tables we can't just put a 14 down here we have this 3 to add so we 7 times 2 is 14 plus 3 is 17 so now we can write the 17 down here because 2 is the last number that we have to deal with and so we have our answer seven times 253 is 1700 and anyone
