a) 23 -(-21) = 23 + 21

• 23 + 21 = 23 + 21

therefore it is TRUE

b) 23 + ( -21) < ( -23 ) + 21

• 23 - 21 < -23 + 21

• 2 < -2

therefore it is FALSE

c) (-5) + (-6) + (-7) > 7 - 77

• -5 - 6 - 7 > - 70

• - 18 > - 70

therefore it is TRUE

d) (-100) + (99) + (-1) = 97 - 99 + 4

• 99 - 101 = 101 - 99

• -2 = 2

therefore it is FALSE

e) 56 - (49 - 7 ) <( 66 -49) - (-7)

• 56 - 42 < 17 + 7

• 14 < 24

therefore it is TRUE

f) 13 - 31 > 3 - 31 - 31

• - 18 > - 59

therefore it is TRUE.
