2.5+1=2
find the inverse of matrix by gauss jordan method
$$\begin{bmatrix} 1 & 2 & 1 \\\\ 2 & 1 & 1 \\\\ 8 & 4 & 3 \end{bmatrix}$$
3^x + 4
x squared - y cubed= 10 squared
-90--6=?
((6-x)/(x+2))^2=((2-x)/(x+6))^2
-90+-6
first four multiples of 12
3 + 3 ^ 2 + 3 ^ 3 +... + 3^n=3/2*(3^n-1) by mathematical induction
