1. Please evaluate and explain your answer using a number line: (-2) + (-5) = Did you change direction or go in the same direction? Was your answer on the positive("+") or negative ("-") side of 0? (please see section 1.1 for further review)
2. Please evaluate and explain your answer using a number line: (-6) + (+2) = Did you change direction or go in the same direction? Simplify by removing unnecessary symbols:_ _ _ _ = _ _ (please see section 1.2 for further review)
3. Evaluate:(-2)³+(-5+8)/ 3 -15(Please see section 1.4an 1.5)
4. If you are adding 2 numbers withdifferent signs (direction), how would you find out the sign and number of the answer? Please evaluate and explain: 2 - 5(please see section 1.2 for further review)
5. Remove grouping symbols and combine like terms: 5(2c -d)-(5c +6d) (please see section 1.9for review)
6. Add:8 + |-11| - (-1) + (-5)(please see sections 1.2 and for further review)
7. Simplify:4(2x - 5)(please see sections 1.6 for further review)
8. When multiplying or dividing signed numbers,count the number of negative signs: Even number of negative signs= + (positive) Odd number of negative signs = - (negative) Evaluate:(-8)(-5)(please see section 1.3 for further review)
9. Evaluate: (-1)(+3)(-2)(-4)(please see section 1.3 for further review)
10. -3 = -1*3 = -1 * 9 = -9 (order of operations) while(-3) = (-3)(-3) = +9 or 9 Evaluate: Z²- X²-XY if X = -2,Y = 3,and Z = -4(please see section 1.8for further review)
