What's four hundred thousand times 4 million
400,000 x 4,000,000
First you have to know how to write those big numbers down.
now 4x4=16 and altogether there are 5+6=11 zeros
so the answer is 16 followed by 11 zeros.
1,600,000,000,000
Which is 1,600 billion if you are from the US
or
1.6 billion if you are Australian.
the US billion is different from the Australian billion.
that is why it is better so use scientific notation for such big numbers.
This is
1.6 x 10
12
