Today in class we reviewed some things from previous years and we also learned some new things about "pemdas" and how it can effect an equasion.

We started off with a Do Now of trying to write down divisibility rules 2 - 10, so here are the answers.
2 - If a number is divisible by 2, it ends in either 0, 2, 4, 6, or 8.
3 - If a number is divisible by 3, the sum of it's digets is divisible by three.
4 - If a number is divisible by 4, then the last two digits of the number are divisible by 4.
5 - If a number is divisible by 5, it either ends in 0 or 5.
6 - If a number is divisible by 6, it must be divisible by both 2 and 3.
7 - The rule is SUPER complicated, so you'll just have to divide.
8 - If a number is divisible by 8, the last three digits of the number are divisible by 8.
9 - If a number is divisible by 9, the sum of it's digits is divisible by 9.
10 - If a number is divisible by 10, the number must end in 0.

Next, we learned about factors.
Factors are integers that divide into another number evenly.
Then, we did some problems to find the factors of a given mumber.

We also learned that prime numbers are numbers that it's only factors are itself and 0.

Later, we learned how exponents are used to show repeated multiplication, it would be alot easier to say 5^7 than 5*5*5*5*5*5*5. You must remember that exponents mean you multiply the. It doesn't mean that you multiply the integer by the exponent. When you write exponents, you write them to the top right of the integer, if it is only miltiplied once you don't have to write anything.

When you add variables, perenthases, and negative numbers in to the process, it can get tricky. When there is a negative variable and it's exponent is even, the product is even. If it's odd, the prodict's odd. If there are parenthases around the negative variable or number, and the exponent ids on the outside, it means that you do the negitive number, times itself as a positive/negative a ceartian amount of times. Parenthases and the exponents effect the equasion and it's answer.
