Things i forgot to do or did wrong on my test:  
 * __** Integers **__-i did very well other then i have to watch and slow down when it comes to the word problems. for example i didnt read question three right and i didnt understand it. ** EX: find the temperature for the last 4 days... -11+7=-4, -4-3=-7, -7+2=-5 so then when you add the (-)s you get -22+2=-20 and then you divide by four and you get -5! **
 * __** Rational numbers **__- i did very good, but i have to watch when i do the bedmas questions. I have to watch my signs and to make sure i didnt mix or forget to put them with their number. for example i made a simple mistake by putting down the wrong deominater. i knew the answer, but i was looking at another number and put that one down instead i have to look over my work more then i have been. ** EX: (7/4)2 - (1/2)(5/6) = 49/16- 5/12. you have to find the same deominaters so you times 49/16 by 3 and you times 5/12 by 4. that will equal 147/48- 20/48. now you go 147-20 which is 127 so your answer will be 127/48!  **
 * **__ Exponents- __** i did really good on this other then a few little mistakes. For exmaple i forgot the rule when multipling keep the base and add the exponent, so when it asked me to do that i did add the exponents but i forgot to keep the base aqnd then so i multiplyied the number as well. On another question i forget to reduce the fraction and make it lowest terms. My last question i got wrong was cause i didnt follow the negative rule. ** EX: (5^-2)(5^7) = 5^5 EX:7/8xy^4 EX: (-5)^3  **
 * **__ Polynomials- __** I added wrong on the one question. I got 19 instead of 9. i just have to watch and see if what i am saying is the same as what i am putting on my paper and make sure that the one on my paper is the right answer. I have to watch and see what i am doing with my variables.
