Question

• 2. Comparati a) |-3 + 71 cu |-31 + 1471; c) -3 + 7 cu |-31 - 1471; b) |-3-7 cu 1-3| + |-71; d) |–3 - 7 cu 1-31- |-7).​

Answer 1

a) |-3+7| = |4| = 4

|-3| + |7| = 3+7 = 10

4 < 10

b) |-3-7| = |-10| = 10

|-3| + |-7| = 3+7 = 10

10 = 10

c) |-3+7| = |4| = 4

|-3| - |7| = -3-7 = -10

4 > -10

d) |-3-7| = |-10| = 10

|-3| - |-7| = 3 - 7 = -4

10 > -4
