Estimate 5,002,319 times 24,625

123,000,000,000 hope this is the right answer

It'd be easiest to round 5,002,319 to 5,000,000 and round 24,625 to 25,000

Now take away the zeros, which would be 9 zeros, and you have:

5 x 25 = 125

Add your 9 zeros back = 125,000,000,000

That would be your estimation
