Question

What is 12x8999? pluss 80000000 and subract 3 billion?
Is that possible?

Answer 1

sure it's possible

12*8999 = 107988
+ 80,000,000 = 80,107,988

80,107,988 - 3,000,000,000 = -2,919,892,012

I did it the good ol'fashioned pencil and paper way.

Most calculators do not go beyond 10 digits of display, so you would know how to use scientific notation. But you still would not get the entire sequence of digits

Answer 2

Yes, it's possible, but you'll have a negative number.

Try it yourself.

Answer 3

12 * 8999 = 12 * (9000 -1)
= 108,000 - 12
= 107,988
=1.07988 * 10^5

8*10^7
= 800 * 10^5

-3 * 10^9 = -30,000 *10^5

so what you have is:
(1.07988 + 800 - 30,000)*10^5
=-29198.92012 * 10^5
=-2,919,892,012

Answer 4

That way I could do it with the calculator :)
