Welcome to my secret math tutor
We're going to go over two examples of front-end rounding if you've never heard of this type of rounding, that's okay
This is basically how it works
We find the largest place value in the number and then we round to that place value
All right. So, let's see how this works. So here's the numbers
728
first identified the largest place value
That'd be this seven guy right here. And then of course check the number just to the right of it
Over here at this two
now the two will tell you whether to keep the seven the same or
Rounded up to an eight
Remember that if this number is four or lower. We'll keep it as a seven
But if it is five or higher, then we'll make that seven and eight
All right. Well since it's just a two that's four or lower. We will leave the seven just as it is
The rest of the numbers we will make a zero
So using front and rounding
728 is approximately
700 just like that
All right, let's do this one more time. So in this next number, we have three thousand nine hundred and thirteen
first find the largest place value
That's the thousands with a three hanging out
okay, check the spot just off to the right and
Determine what we should do with this three. Should we leave it a three or maybe bump it up to a four?
Well, since it's a nine I know to bump this three up to a four
And just like before we'll make the rest of those numbers a zero
So three thousand nine hundred thirteen is approximately four thousand and there you go
That's front and rounding. If you'd like to see some more videos, please visit mysecretmathtutor.com
