Week 3 in Math 10

The thing that I leran in this week is ‘Simplify.Write the final answer with positive exponents’

When I found that I was wrong, I recorded the correct answer and then began to recalculate on the draft paper.Then I’ll be right, and I’ll take the steps on the draft paper and compare with the steps I had before. Found in the calculation process is wrong to see a a, even if the wrong b as a.

In the future calculation will be more careful to prevent the out of this error. And as far as possible to the last and then about, so as to minimize the occurrence of errors.

Remember: Exponents are lazy ! Only bases are affected by the exponents.
