Filling the blanks with sign 

(i) ( -2) + (-9) = -2 -9 = – 11 

and (-2) + (-4) = -2 -4 = – 6 

∴(-2) + (-9) < (-2) + (-4) 

(ii) (- 21) + (- 10) ……….. (- 10) + (- 21) 

(-21) + (-10) = – 21 – 10 = – 31 

and (-10) + (-21) = -10 -21 = -31 

∴ (-21) + (-10) = (-10) + (-21) 

(iii) 45- (-12) (- 12) + 45 

45 – (-12) = 45 + 12 = 57 

and (-12) + 45 = -12 + 45 = 33 

∴ 45- (-12) > (-12) + 45 

(iv) (-14) + (14) ……………….. (-7) + (1) 

(-14) + (14) = -14 + 14 = 0 

and (-7) + (1) = 7 + 1 = -6 

∴ (-14) + (14) > (-7) + (1)
