The table your working at keeps wobbling. You decide to fix it by making a thick pad of paper from folded sheets of paper. Each time you fold a sheet in two, the number of layers doubles. You fold a first sheet of paper 3 times and stick it beneath the wobbly leg. It doesn't quite do the trick, so you fold another sheet of paper 2 times and put it beneath the wobbly leg too. In total, how many layers of paper did it take to prop up the table?

To answer this question and you will use exponents.

When you fold your paper three times, it is represented as two cubed or 2^3.

When you for your other sheet of paper two times, it is represented as two squared or 2^2.

Put Both of these together and you have 8+4 which equals 12.

It will take 12 layers of paper.
