Fill in the blanks to make the following statements  true: (i) \[~\left( -\text{5} \right)+\left( -\text{5} \right)=\left( -\text{8} \right)+\left( ...... \right)\] (ii) \[~-53+......=-53\] (iii) \[\text{17}+......=0\]                     (iv) \[\left[ \text{13 }+\left( -\text{12} \right) \right]+\left( ...... \right)\]\[=\text{13}+\left[ \left( -\text{12} \right)+\left( -\text{7} \right) \right]\] (v) \[\left( -\text{4} \right)+\left[ \text{15 }+\left( -\text{3} \right) \right]=\left[ \left( -\text{4} \right)\text{ }+\text{15} \right]+.......\]                

Answer:

                (i) \[~\left( -\text{ 5} \right)+\left( -\text{ 8} \right)=\left( -\text{ 8} \right)+\left( -\text{ 5} \right)\]           (ii) \[-\text{53}+0=-\text{ 53}\] (iii) \[~\text{17}+\left( -\text{17} \right)=0\]                           (iv) \[\left[ \text{13}+\left( -\text{ 12} \right) \right]+\left( -\text{ 7} \right)\]\[=\text{13}+\left[ \left( -\text{ 12} \right)+\left( -\text{ 7} \right) \right]\] (v) \[(-4)+\left[ 15+(-3) \right]=\left[ (-4)+15 \right]+(-3)\]
