He ripped a piece of paper into three parts, and tore each of those parts into three more parts. if he repeated this action 12 times, how many pieces of paper would he have?

Put this into the Google search window:
3^12 
i think that the answer is 3^12=531441

i need help with dividing negative numbers. for example :what is 2/4.

Can someone please tell me the stepbystep answer to a+6a9=30

a + 6a = 7a
7a  9 = 30
add 9 on both sides
7a=309
7a=21
isolate the a by dividing by 7
a=3 
2*2

i think it is 3*12
