To verify your answers in a math problem it is best to work backwards. For example if you were dividing 4 by 2 and you get the answer 2 you would check it by multiplying 2 time 2. If it is an algebraic equation you can simply substitute the answer back into the original equation. Example with the problem 2X + 1 = 5 and you get the answer X=2 you simply substitute 2 back into the original problem for X...... 2(2) + 1 = 5
