Solve blocks

Given, then constraints, then Find, Minerr, Maximize, Minimize or Odesolve.

Define a guess for each unknown, then a region Given. Below it, type the constraints: equations with =, and inequalities. End with Find, Minerr, Maximize, Minimize or Odesolve, which solves them.

x≔1
y≔1
Given
x2+y2=25
x−y=1
Find(x,y)=(43​)

root finds one zero of an expression without a block, and polyroots all the roots of a polynomial.
