Week 2 Math post

Something I learned in math this week was how to write scientific notation. For example, if you want to write 527000 in scientific notation, it becomes 5.27 × 10^5

You would put the decimal after the first number and then the numbers that come afterwards (that aren’t 0). Then you count how many decimal places the decimal has moved and then use that as the exponent for 10.

Math, Week 1

This week we learned about factors and multiples. Something I found interesting and useful was the method to find the greatest common factors and least common multiples. I thought it was handy how by using the method to find one, you automatically find the other.
