let's try to compute six times 37 and I'll show you one way of doing this and then in future videos we can look at other ways of doing this and think about why this is actually working so what I like to do and this is often called the standard method is take the larger of the two numbers it doesn't matter if you're doing six times 37 or 37 times 6 they equal each other six times 37 is the same thing as 37 times six so what I like to do is I take the larger of the two numbers and I write it on top so I'll write 37 37 and then the smaller of the two numbers which is 6 I'll write it on the bottom and I'll align it by the by the correct place this only has one digit it's in the ones place obviously so I can write I can write to the six I can write the six right over here and I'll write the multiplication symbol like that and this is just another way of expressing 37 times six which is the same thing as six times 37 now what we do is we go with this the first place and this lower number there's only one place here it's only the number six right over here and we're going to multiply that times each of the digits up here so first we will start first we will start with six times seven so we're going to first multiply 6 times 7 well you remember from your multiplication tables 6 times 7 is equal to 42 now we don't just write 42 here at least not in the standard method we wouldn't write 42 here we'd write the 2 and 42 in the ones place so we'd write that right over there and then we'd carry the 4 and 42 up to the tens place now we need to think about what six times three is what six times three is well once again we know 6 times 3 6 times 3 is equal to 18 but we can't just write an 18 down here we still have this 4 to deal with so 6 times 3 is 18 but we've got to we've got to then add the 4 so 6 times 3 is 18 plus 4 is 22 is 22 22 so 6 times 3 then we're adding that 4 right over there and that's how we get our answer so 222
