Conditions of Use
I am writing you a letter about module 1 from math class.
One thing I learned in this module is what experimental and theoretical probability are. Theoretical probability is what you think is going to happen before it happens. It is when you predict something using logical ways. Experimental probability is what actually happened. After you do the experiment the data that you have is the experimental probability.
Another thing that I learned is the order of the operations. The order is pemdas or in other words parentheses, exponents, multiplication, division, addition, then subtraction. We learned that if it is addition and subtraction is all that is left then you just do what is first.
One last thing I learned is exponents. They look like this 2 4. The little number is an exponent. Instead of being 2x4 it is actually 2x2x2x2. Most people thing it is 2x4 but they are wrong. They made exponents to shorten the equation. That is what I learned in module 1.
