how can i Roand my answers to 2 number after decimal point.

That is, Maple shows me only two digits after the decimal point. like this.

with(LinearAlgebra);
K := evalf(Matrix(3, [1/3, -20/3, -20/3, 200/3, 70000/3, 4000/3, 1.44]), 6);

Maple

how can i sort this expresion by index of L

f(15) := expand(((673*L[13] - 485*L[14] - 176*L[15])*h^2 - 90*(L[13] - (13*L[14])/15 - (2*L[14])/15)*x*h)/(12*h^3));

thank you

Maple

how can i remove, zero after dot from my result

restart;
V := 4;
K := 16.56;

H := 0.5;

q1 := evalf(diff(y[1](x), x) = V*y[2](x)/H - K*y[1](x)/H);

Maple

how can i solve this operate differential equation

convert(expand((D[1] - 1)*(D[1]^2 + 2)*y(x) = 0), diff);
dsolve(%)
