Substitution Property of Equality�� ����������� If a = b,
I found a simple proof of the theorem you're trying to prove that uses only 00, b>0, prove that a < b if and only if a^2 < b^2 if and only if sqrt(a) < sqrt(b). If a, b, c are in A.P. So a^2+b^2 = (a+b)^2 - 2ab. a = b means a is equal to b. Multiplication: If a = b then ac = bc. then �a

Multiplying out, this becomes: a^2-2ab+b^2 >= 0 Add 4ab to both sides to get: a^2+2ab+b^2 >= 4ab Factor the left hand side to get: (a+b)^2 >= 4ab Since a, b >= 0 we can take the principal square root of both sides to find: a+b >= 2sqrt(ab) Divide both sides by 2 to get: (a+b)/2 >= ⦠����������������������������������������������������������������������� If

Because if only a = 0, then 0²+b² = -0*b -> b² = 0 -> b = 0 and if only b = 0, then a²+0² = -a*0 -> a² = 0 -> a = 0 Situation 3 and 4: if a and b have the opposite sign, the right hand side is positive: 3. a is negative, b is positive: (-a)²+b² = -(-a)b I had to use the theorem more than once. AB @

If the result of the operation is 0 then we can execute a JEQ which means jump if the output of the operation is equal to zero (see the jump table above).
