1) When adding two rational numbers with the same sign you add their absolute values and keep the sign a) True b) False 2) When adding two rational numbers with different signs you subtract their absolute values and keep the sign of the number with the greater absolute value a) False b) True 3) To subtract rational numbers, you rewrite it as an addition by adding the opposite. Then follow the rules for adding rational numbers a) True b) False 4) 4 - 8 is the same as -4 + 8 a) True b) False 5) 4 - 8 is the same as 4 +(- 8) a) True b) False 6) -19 - 19 a) 0 b) 19 c) 38 d) -38 7) -324 - (-918) is the same as -324 + 918 a) True b) False 8) the difference between 6 and (-12), is represented by which expression a) 6 - 12 b) 6 - (-12) c) -12 - 6 d) 12 - 6 9) the difference between (-12) and 6, is represented by which expression a) 6 - 12 b) 6 - (-12) c) -12 - 6 d) 12 - 6 10) 18 + (-23) a) -5 b) 5 c) 41 d) -41 11) -103 - 51 a) -52 b) 52 c) 154 d) -154 12) 59 - 83 a) 24 b) -24 c) 142 d) -142 13) 5. 8 - 10.3 a) -16.1 b) 16.1 c) -4.5 d) 4.5 14) 82.13 - 100 a) 17.87 b) -17.87 c) 18.13 d) -18.13 15) 15.3 + 2.84 a) 43.7 b) 4.37 c) 1.814 d) 18.14
