<h2>(-7) x (-3) =<u> 21</u></h2>
.... Hope this will help....
Answer:
The factors for 27 are 1,27,3,9
3.482×10^9
Imagine the decimal at the end of the last 0 and move it 9 places to the left
The bracetes means ×
6×6=36 and there is more x
(6x)6=36x
It will be 80/2 and 0/10 you will have to multiply 10*80/2=4000
