What is inverse operation in math? Inverse operation in math is all about using the three numbers in the mathematical equation in different orders and subtracting them from one another to double check the first answer that the kid got in the first trial. Subtraction is one of the different mathematical operations that are found in the world of math and which comes in addition to addition, multiplication and division. There are different techniques and math games that are used for teaching kids subtraction, in this educational video we are depending on the main written technique but Michelle intended to use the help of the building blocks or the cubes as they are sometimes referred to. The inverse operations or the inverse math as it is also known is the technique of changing the position of the numbers of the equation itself in order to double check the answer you have reached. One of the examples is 4 + 1 = 5 that is the answer for the equation that we all know and which the kids could even calculate on their own fingers, but in order for them to double check this answer, they could change the places of the numbers in the equation and thus it would either be 5 – 1 = 4 or else 5 – 4 = 1. This means that the answer that one reached at the beginning is right since the other two equations would bring the two other numbers in the equation.
