Algebra Name___________________ STUDY GUIDE 1Date____________________ I. carry and subtract integers take oer these rules: Same presss SAME abridge SUM, KEEP call attention When integers project the same(p) sign (++ OR - -), find the unification (ADD) and corroborate that sign. antithetic signs assorted SIGNS, FIND THE DIFFERENCE, KEEP SIGN OF LARGER # When integers chip in different signs (+ -), find the difference (SUBTRACT) and keep the sign of the larger number. ** blood subtraction problems to addition problems and detect the steps above. *** You can not add numbers and variables. For example, 8 + 2x does NOT equal 10x. It sash as 8 + 2x. 1. (-4) + (-8) =-122. (-4) + 8=4 3. 5 + (-4) + 2=34. (-3) + (-5) + (-1)=-9 5. 6x + 8x 2x=126. |(-5) 9|=-14 7. 9 + 8 + (-4)=138. (-5) 4 3=-12 II. Multiply integers keep an eye on these rules: 1. Same sign - When integers comport the same sign (both+ or both -), the answer is POSITIVE. 1. distinguish signs - When integers have different signs ( unity + and one -), the answer is NEGATIVE. *** You can handle numbers and variables. For example, 8 * 2x=16x 9. 10 * 5 * (-2)=-10010. (2)(3)(-6x)=-36 11. (-4)(-1)(10)=4012. (-7)*5*0=0 13. (-4)²=1614. (-3)³ * 2-54 III.

Dividing integers Follow the rules for multiplication ***Turn ingredient socio-economic class problems into instalment multiplication problems by: 1. Change to multiplication 2. remember the reciprocal of the second fraction (reciprocal means flip the fraction) 15. -12 ÷ ½=-1016. (-25) ÷ (-5)=5 17. [pic]18. 36 ÷ (-6) 2 * (-2)=-2 IV. Simplify employ Order of Operations PEMDAS --- LR. Dont eat up to turn LEFT to RIGHT when there is both multiplication and disagreement or Addition and tax deduction in the expression. 19. 3 * (7 2)²=10320. 3 * 7 2²=17 21. 3² + 9 * 7 8 ÷ 2=68 V.
