1 Name: Eisenhwer Middle Schl Mathematics Summer Packet Entering 7th Grade Algebra The fllwing is a review f imprtant tpics in 6tr grade that will be needed fr 7th grade Algebra. D nt use a calculatr. It is very imprtant that yu have mastered wrking with decimals, fractins, integers, expressins and equatins fr next year. Mastery in these areas will set yu up fr success next year. A lt f learning is lst in the summer, and every prblem des nt need t be cmpleted. Make sure yu can d a few n each page.these tpics will cme up again and again next year. Cmpletin f the packet is ptinal, and the packet will nt be cllected by yur teacher next vear.

6 and Negative Numbers and negative numbers are als called integers. They are equidistant apart n the line. Fr every psitive number there is an ppsite, a negative number. These carry a sign. This is the negative sign O and a psitive sign (+). When a number with n sign, it is cnsidered t be psitive. Smetimes using a number line is helpful wrking with integers. the ppsite term : : 4. 30: 6. 89: : : adding r subtracting with integers, it is imprtant t pay attentin t the signs. -4+3: 10. 5*9: r (-10): t2. -1,5-7 : t1 : ;: 1s. c10) + (-14) : 2 + (-11): (-181: ;: 19.6*8: e + (-13) : 2r.

7 Muttiplying and Dividing Psitive and Negative Numbers Multiplicatin: Multiplying a negative number with a psitive number gives a negative prduct. Multiplying a psitive number with a psitive number gives a psitive prduct. Multiplying a negative number with a negative number gives a psitive number. Slve: 1. (-8)(e): _ 5. (e) G4) : _ e.

A piitive number divided by a psitive number gives a psitive qutient. Slve: (-8) : 18. (a5) + (-5) : 19. (-14) + 2: 20. (-2r) + 3 : 2t : (-8) : 23. (-32)+8: (-s) : (-8): 26.
