joel_the_boss · Answer

ok first you need to simplify 13−1 to 12$$2 \times \frac{ 12^2 }{ 2}$$

joel_the_boss · Answer

Next Simplify 12^2 to 144$$2 \times \frac{ 144 }{ 2 }$$ Cross multiply and since the denominator is the same it stays 2.$$\frac{ 288 }{ 2}$$ Then you just go ahead and simplify and you get $$288\div2= 144~~~< Answer :) $$

@Joel_the_boss It doesn't matter. He/She can just ignore the steps and take the answer. Does that make sense?
