$\frac{-1\frac{3}{5}}{-\frac{2}{3}}=\frac{\frac{8}{5}}{\frac{2}{3}}=\frac{8}{5}\times\frac{3}{2}=\frac{12}{5}=2\frac{2}{5}$

=45(14)(n)

=630n

Usage 1: Arithmetric operations

such as

5*[23+(5/9)]

Usage 2: Matrices

$\begin{bmatrix} 1 && 2 \\ 3 && 4 \end{bmatrix}$

Using polynomial division

$\frac{x^3-7}{x+5}= x^2-5x+25-\frac{32}{x+5}$

-4x + 8 = -8 

FACTORIZATION

-4(x-2) = -8

x-2 = -8/-4

      = 2

x=4

$\frac{7(23-18)}{(12-5)} = \frac{7(5)}{7} = 5$

As the guest said,

F(n) = Fibonacci[n] + Prime[n]

The next term of 40 would be the 9th term

The next 5 terms are:

F(9) = 34 + 23 = 57

F(10) = 55 + 29 = 84

F(11) = 89 + 31 = 120

F(12) = 144 + 37 = 181

F(13) = 233 + 41 = 274

No,

sqrt(1457786467 = 38180.9699588682529321

1/5 times (5+2)

=7/5

=1.4
