Equation

These objects are one variable first degree equations of all sorts, plus the case of x² = a (which includes the calculus of a right triangle's side's length using pythagorean theorem). Later they might also be equations of higher degree.

The main methods are solve_next_step(), which determines what is the next step in the solving of the Equation, and auto_resolution() which uses solve_next_step() to produce the entire resolution of the Equation.

Possible arg for __init__():

• Equation
• SubstitutableEquality (its length must be 2 and there must be only one variable)
• (Exponented, Exponented)
  These Exponenteds will be the left and right members of the Equation
• (RANDOMLY, <type>)

where <type> can be:
- 'basic_addition': will create x + a = b | a + x = b
- 'basic_addition_r': will create b = x + a | b = a + x
- 'any_basic_addition': will create any of the basic_addition* ones
- 'basic_multiplication': will create ax = b
- 'basic_multiplication_r': will create b = ax
- 'any_basic_multiplication': will create any of the basic_multiplication* ones
- 'any_basic': will create any of the basic*
- 'classic': will create ax + b = c | b + ax = c
- 'classic_r': will create c = ax + b | c = b + ax
- 'classic_x_twice': will create ax + b = cx + d | ax + b = cx | cx = ax + b | b + ax = cx + d etc.
- 'any_classic': will create any of the preceding classic*
- 'classic_with_fractions': will create ax + b = c | b + ax = c where a, b, and c are Fractions
- 'any_simple_expandable': will create an Equation having on one side, in any order, terms of these kinds: a(bx + c) | ±(ax + b) and ax; and on the other side: ax + b | ax | b
- 'any_double_expandable': same as 'any_simple_expandable', plus a second a(bx + c) term on one side randomly chosen

Options:

• name=<string>
• number=<nb>
• variable_letter_name=<string>

Fields:
variable_letter: it's 'x', per default, but you can set another letter here
number: this is the number that will show up when displaying numbered equations' names, like (E1), (E2) etc.
left_hand_side: that's the left hand side of the Equation (as an Exponented)
right_hand_side: that's the right hand side of the Equation (also as an Exponented)
